FREE 31-DAY CHALLENGE · FOR MOUNTAIN BIKERS
BUILD THE ENGINE THAT
OWNS THE CLIMB.
31 days. Your own bodyweight. No gym, no gear. The free leg program for riders who are sick of getting dropped on the climbs - and walking like a question mark after every ride.
Free. No card. Day 1 hits your inbox instantly.
THE MOTOR, NOT THE MACHINE
YOU'LL UPGRADE THE BIKE BEFORE YOU'LL TRAIN THE ENGINE.
Riders will drop two grand on a lighter wheelset and won't spend twenty minutes a week on the legs turning the cranks. But the strongest fork on earth won't save legs that quit halfway up the climb. 31 Legs trains the muscle groups that actually drive the bike - your quads, glutes, hamstrings, and calves - for free, in 31 days.
ACCOUNTABILITY
THE RULES.
NO PASSES.
This isn't a suggestion. It's 31 straight days. Break a rule and you start over at Day 1 — because finishing only means something if you actually finished.
MISS A DAY = BACK TO DAY 1
01. SHOW UP DAILY
Do the day's session as written. No skipped reps, no "I'll double up tomorrow."
02. BODYWEIGHT ONLY
Just you and the floor. Form over everything. Do it anywhere — home, hotel, trailhead.
03. LOG THE RIDE
Note how the climbs feel as the weeks go on. That's the real scoreboard — your legs on the trail.
04. BENCHMARK IT
Record your max wall-sit and thigh measurement on Day 1 and Day 31. Numbers don't lie.
05. 31 STRAIGHT
Miss a day, reset to Day 1. No make-ups. The streak is the point.
MEASURABLE OUTCOMES
DAY 1 VS DAY 31
Three numbers. Log them on Day 1 and Day 31. Let the math prove the work.
01
THE ENGINE
Thigh circumference, both legs (inches / cm). Stronger legs, bigger number.
02
THE WALL SIT
Hold to failure, log the time (min : sec). Watch it climb.
03
YOUR TEST CLIMB
Pick a local climb. Time it on Day 1, time it on Day 31. The number that actually matters on the trail.

I ride more than I train — can I do this?
