Course & elevation
The Colorado Marathon runs net downhill point-to-point, following the Cache la Poudre River down its canyon out of the Rockies and into Fort Collins. Most of the descent comes through the canyon’s opening miles alongside the river before the grade mellows onto the bike path and city streets into town. It’s a steady, runnable downgrade rather than a steep plunge — fast enough for a PR without wrecking the legs.

Key moments
- Mile 1–10The canyon descent beside the Cache la Poudre River — the fastest, most scenic stretch.
- Mile 11–20The grade gentles as you exit the canyon onto the bike path — hold even effort.
- Mile 24–26.2A near-flat finish through Fort Collins — patience early pays off here.
Pacing strategy
Train the downhill so the canyon miles add speed, not strain, and run them on a quick, light cadence without braking. Settle into steady goal effort once the grade eases — even pacing on this profile produces a fast, Boston-legal time and a strong finish in town.

Fueling & hydration
Aid stations roughly every 2 miles with water and sports drink. High, dry Colorado air accelerates dehydration even when it feels cool — drink early and consistently, and keep gels on a fixed schedule through the gentler valley miles.
Weather
Early-May in the Poudre Canyon means a cold, sometimes near-freezing mountain start (snow isn’t unheard of) warming as you descend toward Fort Collins, with strong high-altitude sun and typical spring variability.
