Trail runner · 50K ultra debut
50K finish: 5h33 (target 5h45)
The goal
Finish first 50K under 5h45 with strong second half — previous 30K efforts ended in walk-finish.
What we changed
Long-run progression clamped at +20% week-over-week (per Galloway 10% rule, see /methodology). Back-to-back weekend long runs from week 8. Fueling rehearsal protocol: 60g/h carbs on every run >90min, tested 8 weeks before race day. Strength endurance 1×/week protected even in peak weeks.
Illustrative outcome
Finished in 5h33, ran continuously through km 42–50 where previous races collapsed. No bonk, no GI issues. Ranked top-30% of age group.

| Longest training run | 28km | → 42km |
| Fueling rehearsed | 0% | → 100% of long runs |
| Final 8km pace drop | −45 sec/km | → −8 sec/km |
