Sport, event, distance or format: trail running, 50k

Region, home location or travel radius: within 300 km of Denver, CO

Your level or rating (optional): intermediate, finishing 50k around 7 hours

Date range (optional): May–October 2025

Nine Colorado 50K trail races within 300 km of Denver, with Suffer Better (10 Oct 2026) and Bobcat (17 Oct 2026) closing first

Scope: trail 50K, within 300 km of Denver (straight-line), intermediate runner finishing a 50K in about 7 hours (no entry-standard filter applied; cutoffs flagged). Your stated window, May to October 2025, is already past (today is 6 October 2026), so I read it as the next season: now through October 2027, focused on May to October 2027. Distances from Denver are my approximate straight-line estimates from town coordinates (script: data/dist.py), not driving distances. Access date for all organizer pages: 6 October 2026.

Ranked events

Ranking rule: confirmed cutoff compatible with a 7-hour finish first, then format match, then distance, then open registration. Cutoffs I could not read are marked "unconfirmed", so those events rank lower on eligibility certainty.
