Out-and-back from the ski area base over Mount Werner, along Mountain View and Fish Creek Falls trails to Long Lake, on to Base Camp Trailhead and Dumont Lake, then up Grizzly Creek Road to a card-punch turnaround at the base of the Rabbit Ears rock formation on Rabbit Ears Pass, before retracing the entire route back to the finish at the ski area base. One start wave (plus an over-60/over-50 Early Bird option); no Hare/Tortoise split and no prize money on this distance.
A genuine out-and-back: every aid station except the Rabbit Ears turnaround (no aid, card-punch only) is visited twice, and 'sequence' rather than station name is the identity for the outbound/return pairs. Section-by-section leg mileages in the manual's prose (e.g. '6.0 miles' Start-to-Werner, '6.8 miles' Long Lake-to-Werner-return) do not always sum exactly to the official mile chart's cumulative figures embedded in the same manual (6.4 mi and 5.8 mi respectively for those same legs); the race's own 'Note on Distances' explicitly disclaims trail-mileage precision, so the chart's cumulative numbers are used as the aid_stations' `mile` field and the prose is treated as descriptive only. First climb to Mount Werner gains ~3,500+ ft in about 6 miles. No total elevation gain/loss figure for the 50-mile course was found published anywhere (unlike the 100 mile, which publishes 20,391/20,391); left null rather than estimated.
Two ultramarathons (50 mile and 100 mile) starting and finishing at the base of the Steamboat Ski Area in Steamboat Springs, Colorado, on trails of the Routt National Forest crossing Buffalo Pass and running past Fish Creek Falls, Long Lake and (100 mile only) Emerald Mountain and downtown Steamboat. The 100 mile race runs two divisions from different start times: Hares (competing for prize money, 1 PM start, 30-hour cutoff, no pacers) and Tortoises (9 AM start, 36-hour cutoff, pacers allowed from designated points).
The Run Rabbit Run 50 began in 2007, started by Fred Abramowitz as a charity run benefiting northern Colorado kids and causes; Betsy Kalmeyer designed the original 50 mile course (since changed). Paul Sachs became co-race director in 2008. The 100 mile race, run in Hare/Tortoise divisions and offering the highest purse of any 100-mile trail ultra in the world, began in 2012. Since 2012 the race has donated almost $700,000 to northern Colorado non-profits.

Nobody sees it until we have read it. No account, no sign-in.
This changes nothing on the page on its own. Somebody checks it against the race first.
We want the address of the file the race publishes, not the file. We download it from there so the page can say where the line came from.
We read every one of these and we write back. Every fact here carries the source it came from, and the way a wrong one gets fixed is a person checking it against what you tell us.
NavRun builds your pacing from your own training, then turns it into a plan your crew can follow: when to leave and where to park.
