Your plan should know you had a
terrible night's sleep
Static PDFs break when life happens. Paid apps charge €15-30/month to adapt. Snel adapts to your body, your schedule, and your bad days, free on the core tier, €49/year for Pro founding members.
Most training plans set you up to fail
Rigid Schedules
Miss one workout and the whole plan falls apart. Life doesn't follow a spreadsheet, but most plans demand it.
One Size Fits All
A beginner and a 3:30 marathoner shouldn't be doing the same tempo workout. Yet most free plans treat all runners the same.
Expensive Coaching
Personal coaching costs €100-300/month. Most adaptive apps charge €15-30/month. Smart training shouldn't require a premium subscription, Snel's free tier covers real adaptive coaching, Pro adds the extras.

Every workout teaches Snel more about your fitness, recovery, and potential.
