Why the Quilotoa Loop catches fit people out
The Quilotoa Loop is 35 km over three days with a bed, dinner and breakfast at the end of each one. On paper that is a long weekend. That is the trap. People compare it to a hike they have done, train lightly, and arrive at three consecutive days that gain 2,194 m between them, the biggest ascent of the trek on the last day, on paths that are faint and branch often enough that walkers say a GPS track is essential.
Three things do the damage. The first is the ground: rural paths, farm tracks and roads broken by steep canyon sections, the steepest at a 72 percent grade, loose underfoot, with a stream ford on day 3 that changes with the rain and a narrow path along the crater rim at the end. The second is the order: day 1 is gentle (414 m of ascent over 11 km), day 2 is harder (755 m up, 515 m down), and day 3, the longest, is the hardest: 1,025 m of ascent in 6 to 8 hours to the rim at 3,880 m, on legs that have done two days. The third is the pack: there are no porters, so unless you pay for the mule transfer between hostels, everything you brought is on your back on every step of the ascent.
The stage profile: the classic 3 days from Sigchos to the Quilotoa crater rim, day by day
Training for a trek starts with its shape. The table is the classic northbound 3-day split, Sigchos to Isinlivi, Isinlivi to Chugchilan, Chugchilan to the crater rim, that ends uphill at Quilotoa: what the plan is built from, and what you can check your own version against (many walk it in reverse from Quilotoa to Sigchos, mostly downhill; a fourth day from Quilotoa to Zumbahua, or a warm-up evening near Sigchos, turns it into four days).
| Day | Stage | km | Gain m | Loss m | Hours | Sleep at |
|---|---|---|---|---|---|---|
| 1 | Sigchos (2,852 m) to Isinlivi | 11 | +414 | -350 | 3 to 6 | 2,933 m |
| 2 | Isinlivi to Chugchilan | 12.2 | +755 | -515 | 5 to 8 | 3,178 m |
| 3 | Chugchilan to Quilotoa village on the crater rim (3,866 m) | 11.8 | +1,025 | -342 | 6 to 8 | trek ends |
About 35 km, 2,194 m of ascent and 1,207 m of descent over three days. Two nights in hostels, at Isinlivi and Chugchilan, the highest at Chugchilan, 3,178 m; dinner and breakfast are included and the hostels sell box lunches (carry day 1's lunch from Sigchos). No porters; you carry your own pack, or pay for a mule to move your bag between the hostels. Daily figures differ by operator and by camp choice; the table follows the canonical trek database (two independent itineraries plus a terrain measurement of the route, checked 2026-10-18).
Read the table as a training brief. Day 1 is the warm-up: 11 km with 414 m of ascent to Isinlivi at 2,933 m. Day 2 is the canyon day: 755 m up and 515 m down, the biggest descent of the trek, to Chugchilan at 3,178 m. Day 3 is the long one: 11.8 km, 1,025 m of ascent, 6 to 8 hours, the stream ford, then the final pull to the rim at 3,880 m, 702 m above the Chugchilan hostels. The rising order of the days, the pack and the route finding are what the plan is built around. Altitude is only part of it: the highest night is 3,178 m and the rim is reached on the last afternoon.
What a trek asks that a summit does not
A one-day objective has one hard day and a walk out. The Quilotoa Loop has three days that get harder in order, with your own pack on, and its biggest ascent at the very end. That is a different physiology, and a plan built for a single hard day misses it.
- Consecutive days that build, not one day. Three days, no rest day, two in a row over five hours, each gaining more than the last (414, 755, 1,025 m). Fatigue accumulates faster than fitness recovers, so the plan trains back-to-back long days, not a single rehearsal.
- The biggest ascent comes last. 1,025 m on day 3, more than a typical day's 755 m, to a rim at 3,880 m, on legs that have done two days. The Saturday long days are built to finish with their steepest ascent, not to start with it.
- Loose descents in the canyons. 1,207 m of descent in total, 515 m of it on day 2 on steep, loose canyon paths. Eccentric leg strength is not an add-on; it is what keeps the canyon days from costing the rim day.
- Your own pack, every step. No porters: your own pack hostel to hostel, or a lighter one if you pay for the mule transfer between the hostels. Train with the weight you will carry from the middle of the plan, not in the last fortnight.
- Route finding and weather, more than altitude, are the risk. Paths are faint and branch, walkers say a GPS track is essential, the day 3 stream ford rises with rain, and afternoons are often cloudy or wet, so early starts matter. Fitness buys the margin to be on the rim before the afternoon weather.
Physical benchmarks to hit before the Quilotoa Loop
The Quilotoa Loop loads five physiological systems. A real preparation plan trains all five, with the rising order of the days and the final ascent at the centre.
Altitude: what the itinerary handles and what training cannot
Altitude is real on the Quilotoa Loop but it is not the main limiter. The high point is the crater rim at 3,880 m (12,730 ft), reached on the last afternoon; the nights are at 2,933 m in Isinlivi and 3,178 m in Chugchilan, so only one night is above 3,000 m, and the route gains height gradually from 2,852 m at Sigchos. Most people feel the rim as harder breathing on the final ascent rather than as illness, which is one reason to arrive in the sierra a day or two before you start rather than straight from sea level. Training does not acclimatise you; what it does is lower the cost of each hour so the thin air on the last 702 m to the rim costs you less.
What replaces altitude as the limiter is the ground, the route and the weather. Paths are faint and branch, so carry a GPS track and know how to follow it; the canyon sections are steep and loose, the crater-rim path is narrow, the day 3 stream ford rises with rain, and afternoons are often cloudy or wet, so start early. The fitter you are, the earlier you are on the rim and the more margin you keep. Our hiking training guide covers the base, and the altitude acclimatisation guide explains what the rim's height does and does not do.
The 12 to 16 week Quilotoa Loop preparation timeline
The block runs backwards from your departure date. Six phases, each with a distinct target. The hardest training weeks land three to six weeks before you fly, not in the final taper.
- Weeks 1 to 4 · Aerobic base. Three to four Z2 sessions a week, 45 to 90 minutes. Walk, hike, run, cycle; weight on feet preferred.
- Weeks 5 to 8 · Base plus strength plus the weekend pair. Add one eccentric leg session a week and make the weekend two consecutive Z2 hikes, with your own pack from here on and Saturday's biggest ascent at the end of the day.
- Weeks 9 to 11 · Muscular endurance. Saturday grows to 4 to 5 hours with 900 to 1,100 m of gain (a typical day is 755 m, the biggest 1,025 m), the Sunday walk stays long. Stairs and incline if you have no hills.
- Weeks 12 to 13 · Big-day rehearsal. One 6 to 8 hour day with 1,025 m of ascent, most of it in the second half, the real pack and the real food: the shape of day 3.
- Week 14 · Last big weekend. One more back-to-back pair at full length, then the taper begins.
- Weeks 15 to 16 · Taper. Volume drops 30 to 50 percent, one short sharp session stays, legs arrive fresh in Sigchos.
A weekly distribution that works
The polarised principle applies: most of the week at low intensity, one hard session, and the weekend pair that makes a trek plan different from a summit plan, two long days back to back (Seiler & Kjerland, 2006). A representative week, 10 weeks out from Quilotoa Loop:
- Mon · easy 60 min Z2 walk or run
- Tue · threshold intervals, 4 x 4 min Z4, or hill repeats
- Wed · rest or 30 min mobility
- Thu · 60 to 90 min stairs or treadmill incline, Z2, pack on, 400 to 600 m of gain
- Fri · eccentric strength: weighted step-downs, split squats, calf and hip work, 40 min
- Sat · long Z2 hike, 4 to 5 hours, 900 to 1,100 m of gain with the steepest ascent at the end, full pack
- Sun · second long Z2 walk on tired legs, 2.5 to 3.5 hours, pack on (the back-to-back day)
Roughly 80% of weekly volume sits at Z1 to Z2, with one hard intensity session and the back-to-back weekend. Vertical and hours accumulate progressively across the block. The deeper rationale is in our heart rate zones guide; the descent work is explained in eccentric descent training.
How TTM trains the plan to the Quilotoa Loop
Five things the plan is built around
- Fitness target · The Quilotoa Loop is set to a fitness target the model associates with walking the three days with margin. Your plan is engineered to reach that level by your departure date, and the readiness number tells you how far off you are, with the basis stated.
- Stage-shaped long days · The weekend long days are sized from the itinerary above, not from a generic hiking template: hours and gain grow toward the 755 m typical day, then toward the 1,025 m ascent of day 3.
- Back-to-back loading · The plan schedules consecutive long days in the build and specific phases because that is the demand. Multi-day durability is scored as its own component of your readiness.
- Descent eccentric load · Eccentric strength and downhill repeats are programmed from the middle of the plan to prepare for 1,207 m of descent on loose canyon paths, not bolted on at the end.
- Weekly recalibration · Every Sunday the plan re-reads your watch data (Garmin, Suunto, Coros, Polar, Apple Health) and adjusts the next week: missed sessions, a cold, a bigger-than-planned weekend, all accounted for.
When you tell TTM your trek is the Quilotoa Loop and your departure date, the plan is built backwards from that date with the stage profile above engineered in, and it recalculates every week, every Sunday, against your actual training data from your watch. You do not need to assemble the pieces yourself.
Quilotoa Loop: quick answers
How fit do I need to be for the Quilotoa Loop?
Fit enough to walk about 6.5 hours a day, and 6 to 8 on the last, for three days in a row with your own pack, on rough rural paths and steep canyon sections, finishing with a 1,025 m ascent to the crater rim at 3,880 m. No technical skill is needed; route finding is the skill that matters, so carry a GPS track. The benchmark that matters most is consecutive days with a pack: if two long hill walks on a weekend, the second ending with a steep ascent, leave you fine on Monday, you are close. If one long hike wrecks you for three days, you have a durability gap, and that is what 12 to 16 weeks of training fixes.
How many weeks does it take to train for the Quilotoa Loop?
Twelve to sixteen weeks from a base of two or three sessions a week. Less if you already hike long days with a pack regularly; more if you are starting from little. The hardest training weeks should land three to six weeks before you go, with a two week taper after them.
What is the hardest day of the Quilotoa Loop?
Day 3, Chugchilan to the crater rim, is the longest and the hardest: 11.8 km, 1,025 m of ascent, 6 to 8 hours, a stream ford that rises with rain, then the final pull onto the rim at 3,880 m. Day 2, Isinlivi to Chugchilan, carries the biggest descent, 515 m on steep, loose canyon paths, with 755 m of ascent after it. Walked in reverse from Quilotoa, the route is mostly downhill and the rim comes first.
Do I need to train with a weighted pack for the Quilotoa Loop?
Yes, with the pack you will actually carry. There are no porters; the hostels provide dinner, breakfast and box lunches, so the load is your clothes, water and gear for three days. Mules can carry your bag between the hostels for a fee, which turns it into a daypack. Either way, carry the real pack on every long training day from the middle of the plan.
Is altitude a problem on the Quilotoa Loop?
Rarely as illness, often as breath. The rim is 3,880 m, the highest night is 3,178 m, and the route rises gradually over three days from 2,852 m. Most people notice harder breathing on the final ascent and little else; arriving in the sierra a day or two early helps. The limiters are the final-day ascent, the loose ground, the route finding and the weather, not the air.
When should I walk the Quilotoa Loop?
June to September is the dry and busiest season; April to May and October to November are drier shoulder months, and the route is walkable all year. Afternoons are often cloudy or wet, so start early every day. There is no permit or fee for the walk; book the hostels in Isinlivi and Chugchilan, and plan the 12 to 16 week block backwards from your start date.
Is the Quilotoa Loop the same as the Quilotoa Traverse?
Yes. Quilotoa Loop, Quilotoa Traverse, the Sigchos to Quilotoa trek and the Quilotoa Lake Trail all name the same 3-day route between Sigchos and the crater rim through Isinlivi and Chugchilan, in either direction. It is a traverse, not a circle; the bus back from Quilotoa runs to Latacunga, where hostels store luggage.
Common questions about training for the Quilotoa Loop
How fit do I need to be for the Quilotoa Loop?
Fit enough to walk about 6.5 hours a day for three consecutive days with your own pack on rough rural paths and steep canyon sections, finishing with a 1,025 m ascent to the crater rim at 3,880 m in 6 to 8 hours. The benchmark that matters most is two long hill walks on a weekend, pack on, the second ending with a steep ascent, that leave you fine on Monday.
How many weeks does it take to train for the Quilotoa Loop?
Twelve to sixteen weeks from a base of two or three sessions a week. The hardest training weeks land three to six weeks before you go, followed by a two week taper.
What is the hardest day of the Quilotoa Loop?
Day 3, Chugchilan to the crater rim: 11.8 km, 1,025 m of ascent, 6 to 8 hours, ending on the rim at 3,880 m. Day 2 has the biggest descent (515 m on loose canyon paths).
Is the Quilotoa Loop the same as the Quilotoa Traverse?
Yes. Quilotoa Loop, Quilotoa Traverse, Sigchos to Quilotoa trek and Quilotoa Lake Trail all name the same 3-day hostel-to-hostel route through Isinlivi and Chugchilan, walked in either direction.
Do I need to train with a weighted pack?
Yes, with the pack you will actually carry. There are no porters; mules can move your bag between the hostels for a fee, which leaves you a daypack. Carry the real pack on every long training day.
Is altitude a problem on the Quilotoa Loop?
Rarely. The rim is 3,880 m and the highest night is 3,178 m; most people feel harder breathing on the final ascent and little else. The limiters are the final-day ascent, the loose ground, the route finding and the weather.
Do I need a guide or a permit?
No permit or fee for the walk, and no guide requirement. Many people walk it self-guided; the paths are faint and branch, so carry a GPS track. The hostels in Isinlivi and Chugchilan include dinner and breakfast and sell box lunches; Sigchos has the last shops before them, so carry day 1's lunch.
When is the best time to walk the Quilotoa Loop?
June to September, the dry season; April to May and October to November are drier shoulder months and the route is walkable all year. Afternoons are often cloudy or wet, so start early.
Which direction should I walk the Quilotoa Loop?
The classic direction starts in Sigchos and ends uphill at the crater, which puts the 1,025 m ascent on the last day and is the version this page is built on. Walked in reverse from Quilotoa to Sigchos the route is mostly downhill, and the demand shifts to the knees. A fourth day from Quilotoa to Zumbahua, or a warm-up evening near Sigchos, turns either version into four days.
How hard is the Quilotoa Loop?
The Quilotoa Loop is 3 days: 35 km, 2,194 m of ascent and 1,207 m of descent. A typical day is about 6.5 hours with 755 m of ascent; the longest, day 3, is 6 to 8 hours with 1,025 m up and 342 m down. The high point is 3,880 m. One of the two nights is above 3,000 m, so altitude is part of the difficulty and the itinerary's acclimatisation, not your fitness, is what handles it. You carry your own pack every day. Rural paths, farm tracks and roads with steep, loose canyon sections and a narrow crater-rim path; faint, branching paths make route-finding the main difficulty, the day 3 stream ford varies with rain, and the walk finishes at about 3,900 m. There is no rope work on the standard route. In training terms the difficulty is consecutive days, the daily vertical, the descents and the pack, and 12 to 16 weeks from a base of two or three sessions a week covers it; the 16-week Quilotoa Loop training plan is the fixed version.
How long is the Quilotoa Loop?
The Quilotoa Loop is 35 km in 3 days, about 14 to 22 hours of walking in all, with 2,194 m of ascent and 1,207 m of descent, from Sigchos (2,852 m) to Quilotoa village (3,866 m). That is the standard itinerary; operators move camps and merge days, which changes individual days, not the total.
Can I do the Quilotoa Loop without training?
Not well, and for most people not safely. The Quilotoa Loop asks for 3 consecutive days, about 6.5 hours and 755 m of ascent on a typical day and 6 to 8 hours on the longest, and one night at or above 3,000 m where fitness does not replace acclimatisation but is what keeps reserve for it. Untrained walkers are the ones the later days hurt: fatigue accumulates faster than fitness recovers, the 1,207 m of descent lands on quads that have never braked for hours, and the gap shows on the longest day, not the first. Twelve to sixteen weeks from a base of two or three sessions a week is enough for most people; the 16-week Quilotoa Loop training plan is the fixed version and the app builds the personalised one backwards from your departure date.

The takeaway
The Quilotoa Loop is rarely a fitness problem in the abstract. It is a shape problem: the people who reach the crater rim with legs to spare trained for three consecutive days that get harder in order, their own pack and a 1,025 m ascent at the very end, not for a long weekend walk. Train the week, not the day, finish the long days with their steepest ascent, and carry the pack from the middle of the plan.
