How Summit Check works
Most climbers check one thing at a time: a readiness test here, a heart rate calculator there. Summit Check strings our free tools together for one objective. You pick the peak and your summit date once, choose which tests to take, and every test reads them from there. Nothing is re-entered.
The muscular endurance, Zone 2 and fuel tests are the same as their standalone tools, with the same inputs and the same formulas, so your numbers match: the muscular endurance calculator, the Zone 2 heart rate calculator and the fuelling calculator. The skills check uses the route skills on each peak training page, so it is available for our 88 guided peaks. Every other test works for any peak in our database or one you enter yourself.
Your biggest gap is picked by a simple rule. If your summit date is shorter than your current fitness needs, time is the gap, because training cannot add weeks. Otherwise we compare every 0 to 100 score from the tests you took (the five readiness profile areas, your skills score and your muscular endurance score) and flag the lowest one. Zone 2 and fuel give you targets rather than scores, so they only count when nothing else was tested.
Common questions
What is Summit Check?
Summit Check runs the Train to Mountain free tools one after the other for a single peak: readiness, a skills check, muscular endurance, Zone 2 heart rate and a summit-day fuel plan. You choose which tests to take, enter your peak and summit date once, and get one summary with your biggest gap. The full report, with what to do about each gap, comes by email.
Do the results match the standalone tools?
Yes. The muscular endurance, Zone 2 and fuel tests use the same inputs and formulas as their standalone tools: the muscular endurance calculator, the Zone 2 heart rate calculator and the fuelling calculator. The readiness test uses the same questions and formulas as our original readiness calculator. The skills check uses the same route skills shown on each peak training page. The same answers give the same numbers.
Why is there no readiness score?
From questionnaire answers we can size the runway in weeks and the weekly training load your peak asks for, but not measure your readiness. A readiness number needs your actual training data, so the readiness test shows your runway, your weekly load and a five-area profile instead of a made-up score.
What happens to my answers?
The tests run in your browser. If you ask for the full report by email, we store your email, your peak, your summit date and a link to your report. The link holds your results rather than your raw answers (no weight, age or health answers), and anyone you share it with can open it.
How Trek Check works
Most trekkers check one thing at a time: a readiness test here, a heart rate calculator there. Trek Check strings our free tools together for one trek. You pick the trek and your start date once, choose which tests to take, and every test reads them from there. Nothing is re-entered.
The muscular endurance, Zone 2 and fuel tests are the same as their standalone tools, with the same inputs and the same formulas, so your numbers match: the muscular endurance calculator, the Zone 2 heart rate calculator and the fuelling calculator. The readiness test adds up to three trek checks from the stage profile in our trek database: your longest recent day against the trek's hardest day, your back-to-back history against its days in a row over five hours, and, when the trek sleeps above 2,500 m, your altitude history against its highest night. It works for the 24 treks in the database, from Kilimanjaro to the Tour du Mont Blanc, or for a trek you enter yourself.
Your biggest gap is picked by a simple rule. If your start date is shorter than your current fitness needs, time is the gap, because training cannot add weeks. Otherwise we compare every 0 to 100 score from the tests you took (the trek checks, the five readiness profile areas and your muscular endurance score) and flag the lowest one. Zone 2 and fuel give you targets rather than scores, so they only count when nothing else was tested.
Common questions
What is Trek Check?
Trek Check runs the Train to Mountain free tools one after the other for a single trek: readiness, muscular endurance, Zone 2 heart rate and a fuel plan for the hardest day. You choose which tests to take, enter your trek and start date once, and get one summary with your biggest gap. The full report, with what to do about each gap, comes by email.
Where do the trek numbers come from?
From our trek database: a standard itinerary per trek, built from independent sources plus a terrain measurement of the route and checked on 2026-10-18; the few treks with rows still under review say so in the result. For each trek it holds the stage profile (hours, ascent, descent and high point per day), the longest run of days over five hours and the highest night. Trek Check reads the hardest day, the days in a row and the sleeping altitude from there. Kilimanjaro, for example, is 7 days with a 10 to 14 hour summit night that gains 1,222 m and descends 2,827 m.
Do the results match the standalone tools?
Yes. The muscular endurance, Zone 2 and fuel tests use the same inputs and formulas as their standalone tools. The readiness test uses the same questions and formulas as our readiness calculator, with the trek's high point setting the runway and its hardest day setting the weekly load. The same answers give the same numbers.
