⚡ SIGNATURE CHALLENGE
The distance is the story

2600 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

Kagoshima, Japan in autumn (October): 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~650 km

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

02
Day 2 — Settling Into the Rhythm~1300 km

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

03
Day 3 — The Crux~1950 km

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

04
Final Push — Home Stretch2600 km

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

WHAT TO FEAR

  • [!01]Mental low point on the long, lonely middle section
  • [!02]Resupply gaps — carry more food than you think
