Gary, South Dakota → Hager City, Wisconsin in mid-summer (August): expect mild conditions — pack for variable weather. Always check 7-day forecast race week and pack a packable shell.
PACING PLAYBOOK
Resist the urge to push. Your race starts in 48 hours, not at km 0.
Eat early, eat often. Sleep matters more than watts now.
Mental low point. Stick to the plan. Most riders bonk here mentally before physically.
Save matches. The finish line will reveal itself when you stop chasing it.
