WEATHER PLAYBOOK

Stanley, Idaho in mid-summer (June): 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~75 km

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

02
Day 2 — Settling Into the Rhythm~150 km

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

03
Day 3 — The Crux~225 km

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

04
Final Push — Home Stretch300 km

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

WHAT TO FEAR

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