⚡ SIGNATURE CHALLENGE
The distance is the story

729 km is not a race — it's an expedition. Pacing is decided by hours, not km splits, and sleep strategy matters more than power.

WEATHER PLAYBOOK

Mytholmroyd, West Yorkshire in spring (May): expect mild conditions — pack for variable weather. Always check 7-day forecast race week and pack a packable shell.

PACING PLAYBOOK

01
Day 1 — Opening Effort~182 km

Resist the urge to push. Your race starts in 48 hours, not at km 0.

02
Day 2 — Settling Into the Rhythm~365 km

Eat early, eat often. Sleep matters more than watts now.

03
Day 3 — The Crux~547 km

Mental low point. Stick to the plan. Most riders bonk here mentally before physically.

04
Final Push — Home Stretch729 km

Save matches. The finish line will reveal itself when you stop chasing it.

WHAT TO FEAR

  • [!01]Late-race climbs after the legs are gone
  • [!02]Mental low point on the long, lonely middle section
  • [!03]Resupply gaps — carry more food than you think

▌ INCOMING TRANSMISSION

The wind off the water defines the day at Source to Sea Gravel Trail. You either pace by perceived effort or you pay.

▌ INCOMING TRANSMISSION

European gravel has a different rhythm — the long lunch stops, the espresso at km 60, the post-race beer that lasts hours. Source to Sea Gravel Trail captures that perfectly.
