⏵ Course guide · Road weekend, Ruidoso NM
Ruidoso RunFest is a two-day road race weekend in the New Mexico mountain town of Ruidoso, put on by Wanderlust Running with the Village of Ruidoso Parks & Recreation. Friday brings a 5K and Kids fun run, then Saturday is the main event: the Ruidoso Marathon and Half Marathon, alongside the State-Forty-Seven Road 47K/50K, billed as New Mexico's only premier road 50K. I will walk you through the weekend and the course first, then give you a pacing and fueling plan for racing a road distance at altitude. There are free calculators along the way to dial in your own numbers.
These facts come from the official Race Roster listing and wanderlust.run. Total elevation gain and the overall Marathon, Half, and 47K cutoffs are not published, so confirm both directly with Wanderlust Running before you register or race.
This is a two-day event with a festival feel and a serious distance option buried inside it, all on road, all at high altitude.
Friday evening is the warm-up act, a Pizza Hut 5K and a Kids 1K fun run, packet pickup for the whole weekend runs 2:00 to 6:00 PM at Wingfield Park. It sets a community, festival tone, with local bands, food trucks, and a beer garden, before Saturday gets serious.
Saturday is the real race day: the Ruidoso Marathon and Half Marathon in their 7th year, run alongside the State-Forty-Seven Road 47K/50K presented by Bluebird Running in its 3rd year. The 47K/50K is the standout here, because it is explicitly a road ultra, not a trail one, which the race calls New Mexico's only premier road 50K. If you want ultra distance without technical trail footing, this is a genuinely uncommon option.
The 47K earns its own awards, but if you want the full 50K, you add one more loop, and that loop has to be done by 2:00 PM. That is the only published cutoff for the whole event, so if you are chasing the 50K specifically, build your morning around clearing that deadline rather than assuming you have all day.
Road terrain removes the grade problem, but Ruidoso's altitude, around 6,900 feet, does not go away just because the surface is pavement.
Your sea-level road pace will not hold at 6,900 feet, especially over the marathon and 50K distances. Use a recent race result to set an honest goal pace with the race-equivalent calculator, then build a mile-by-mile plan with the race-time calculator so you have a real target instead of a flat-ground guess.
The extra loop deadline is the one hard number on this course, so work backward from it. Know what pace gets you to the loop decision point with real margin, not just barely inside the window, since a road ultra at altitude can slow more than you expect in the closing miles.

The Marathon and the Road 47K/50K are both long enough, at altitude, that a real fueling plan matters more than it would at sea level.
Set your usual per-hour carbohydrate schedule for the distance you are racing, and know your exact gel count going in. Ruidoso's altitude can blunt appetite the same way any mountain-town race does, so the trick is keeping intake steady from early rather than trying to catch up later when your stomach has already started to protest, especially deep into the 47K/50K.

It is a two-day festival. Friday evening brings a Pizza Hut 5K and a Kids 1K fun run. Saturday is the main event: the Ruidoso Marathon and Half Marathon, now in their 7th running, plus the State-Forty-Seven Road 47K/50K presented by Bluebird Running, now in its 3rd year. You can run the Friday 5K, any single Saturday race, or chase the 'Back to Back' charm by doing both.
The base distance is a 47K, and it earns awards on its own. If you want the full 50K, you add one extra loop, but that extra loop has to be completed by 2:00 PM, which is the only published cutoff for the race. Decide before the gun whether you are going for the 47K or committing to the extra loop, since that 2:00 PM deadline is firm.
Yes. Unlike most 50Ks, which are trail races, this one runs on road, and it is billed as New Mexico's only premier road 50K. That distinction matters for training: prepare with road-specific long runs and pacing rather than trail-focused vert and technical footing work, even though you should still respect the altitude of a Ruidoso race.
Ruidoso sits around 6,900 feet, which is a real factor for a marathon-distance or longer effort if you are coming from low elevation. The race does not publish a total elevation gain figure, so treat the altitude, not a specific climb, as the thing to respect and train for.
The only cutoff the race publishes is the 2:00 PM deadline to complete the extra loop if you are going for the full 50K instead of the 47K. Overall time limits for the Marathon, Half Marathon, and base 47K are not published on the official pages, so confirm current cutoff details with Race Roster before you commit to a goal time.
Plan for a multi-hour road effort at high altitude, which is different from fueling a sea-level race. Set your usual per-hour carbohydrate and sodium schedule, but expect the thinner air to blunt your appetite somewhat, especially over the 50K distance, so practice eating steadily rather than waiting until you feel behind. Run your own numbers with the free marathon fueling calculator or ultra fueling calculator depending on your distance.
