8-week beginner plan: your first 5 km obstacle race
Three sessions a week to take you from regular exercise to finishing a 5 km mud run with confidence.
Who it's for
You can jog for 20 minutes and want to finish a 5 km race with 10–20 obstacles without walking every hill.
Weekly structure
Three sessions, never on back-to-back days.
- Session A – Run: 20–35 min easy jog, building 5 minutes every two weeks.
- Session B – Strength circuit: 3 rounds of 10 squats, 8 push-ups, 10 lunges, 20 s dead hang, 30 s plank.
- Session C – Trail mix: 30 min on grass or trail with 6 × 30 s uphill efforts and bear crawls.
Weeks 1–4
Focus on consistency. Hang from a bar or tree branch at every session and add 5 seconds each week.
Weeks 5–8
Run in your race shoes on wet ground. Add a 10 kg carry (rucksack or bag) for 2 × 100 m. Week 8 is lighter: two short runs and rest two days before race day.
