Your free half marathon
training plan
Not a static PDF. A living, adaptive plan that evolves with every run you complete.
The half marathon is the sweet spot: long enough to demand real training, short enough to recover from quickly. But most free plans treat every runner the same. Snel generates a personalised 12-week plan calibrated to your VO2max, then adapts it week by week based on how you're responding to training. Coach-level plans, zero cost.
What you get
Personalised VO2max zones
Easy, tempo, threshold, interval and rep paces calculated from your race history or current easy pace. Every workout has exact targets.
12-week periodised structure
Foundation, Build, Specific, and Taper phases designed for the half marathon distance. Peak at the right time.
Weekly adaptation
Your plan adjusts based on RPE feedback, pace trends, and missed sessions. No more guessing whether to push or pull back.
Injury prevention & load monitoring
Training load tracking, fatigue signals, and automatic volume adjustments to keep you healthy through race day.

Why not just download a PDF?
PDFs don't adapt
Got sick and missed a week? A PDF doesn't know. Snel restructures your remaining weeks to keep you on track for race day.
PDFs don't know your zones
"Run at tempo pace" means nothing without your personal threshold. Snel gives you exact pace ranges for every workout.
PDFs can't prevent injuries
Snel monitors your training load and fatigue signals. When the numbers don't add up, it reduces volume before you break down.
