CERVIDAE

Includes the following events: HEINEN, KEPROS, and LUCKY PEAK
🦌 Cervidae
Short, steep, and unrelenting. This out-and-back beast is known for punching above its weight. The trail will have your quads screaming on the way up and your knees praying on the way down.

* note - we’ve recently had friends receive some pretty hefty tickets for having dogs off leash here.

Distance: ~4.5 miles

Elevation Gain: 2,000+ ft

HEINEN

Includes the following events: CERVIDAE, KEPROS, and LUCKY PEAK
🏔️ Heinen
A true grind, Heinen is for those who don’t mind switchbacks that feel like staircases and views that’ll stop you mid-stride (if the altitude doesn’t first).

Distance: ~9 miles

Elevation Gain: 3,700+ ft

KEPROS

Includes the following events: CERVIDAE, HEINEN, and LUCKY PEAK
⛰️ Kepros
An undulating ridge run with relentless exposure and some of the best views in the series. Long, scenic, and deceptively tough.
