Emphatically yes — a Grind is a genuine hard training session: forty-five-plus minutes of sustained climbing effort with 800 metres of gain, taxing exactly the leg strength-endurance and engine that structured training builds on purpose. Anyone logging it as "just a hike" is under-counting their week.
The more useful question is what it counts as — because the Grind is a specific stimulus with specific gaps, and slotting it correctly into a week matters more than crediting it.
What a Grind actually trains
It is a climbing interval session wearing hiking clothes: sustained effort near threshold for most people, step-up strength-endurance by the thousands (2,830 of them), and calves, glutes and quads loaded continuously in the pattern step-up training rehearses indoors. For time-crunched fitness, one weekly Grind delivers what a hard studio conditioning session delivers — enough that treating it as one of the week's two-or-three genuinely hard days is the correct accounting, with the recovery spacing that implies.
What it misses — the honest gap list
Three gaps keep the Grind from being a complete program. The descent: the gondola takes it, so the eccentric leg strength that real mountain days demand goes untrained — Grind-fit hikers still get wrecked by descents elsewhere. The upper body and trunk: climbing stairs builds neither pulling, pushing nor carrying strength. Progressive load: the mountain never gets heavier; once your time plateaus, the stimulus does too, which is exactly the progression problem structured strength work exists to solve. The Grind plus two strength sessions is a genuinely strong week; the Grind alone is one excellent ingredient.
Slotting it into a real week
Count it as a hard day and space accordingly: Grind Saturday plus strength Monday-Wednesday is a clean shape; Grind stacked onto Friday intervals is the hard-plus-hard pattern the doubles answer warns about, spread across two days. In season, one to two ascents a week is the sustainable dose for most (the climbing-block arithmetic from the race plan applies); off-season, the indoor translation is incline treadmill work and step-ups, which is how the fitness winters over. And the weekly Grind makes a superb progress instrument: same mountain, same steps, your improving time — a benchmark with a gondola at the top.
Common questions
Can the Grind replace my leg day?
It replaces the conditioning half, not the strength half — endurance under bodyweight is not progressive loading. Legs chasing strength still need the loaded patterns.
How many calories does a Grind burn?
Enough to be a genuinely hard session, and — per every honest energy page here — not enough to out-climb a celebratory chalet meal. Train for the fitness; let the kitchen handle the deficit.
Is doing the Grind twice in a row a good workout?
Doubles are a real Grinder tradition and a big withdrawal — treat a double as the week's dominant session, not an add-on. Multi-lap ambitions belong on the racing-and-events end of the spectrum.
