Recurring Half Marathon races near Fort Collins-Loveland

Races that repeat — weekly, monthly or yearly

The Long View Marathon

The Long View Marathon runs point to point between Fort Collins and Loveland in northern Colorado. The full marathon begins at Edora Park and concludes at Fairgrounds Park. The same finish area hosts the half marathon, which starts at Fossil Creek Park, and a 5K centered on Fairgrounds Park. The races occur in October, with staggered morning starts for the marathon, half marathon, and 5K. The route incorporates sections of the Long View and Front Range bike paths, meaning the longer races utilize a paved-path corridor instead of a closed downtown loop. Packet pickup is available at Altitude Running in Fort Collins prior to race day and at each race’s start area on race morning, subject to a strict cutoff. Marathon and half-marathon prizes feature custom works by local artist Amy Hayman, gift cards to local businesses, overall awards, and age-group prizes; the 5K offers overall and masters awards.

Westy Half & 5k

The Westy Half & 5k is a fall running event in Westminster, Colorado, located at 10600 Westminster Boulevard. It features two distances: a half marathon for those seeking a longer morning run, and a 5k for participants preferring a shorter race. The event is part of the Hometown Race Series, which organizes half marathons and 5k races in communities outside the primary Denver and Boulder metro regions. A notable aspect is the 5k medal policy: all 5k finishers receive a medal, a practice that remains infrequent for this race distance.

Louisville Trail Race

The Louisville Trail Race offers half marathon, 10K, and 5K distances on dirt trails near Louisville Community Park in Louisville, Colorado. It provides a Front Range trail running experience, allowing both experienced and newer trail runners to select a course suited to their abilities. The routes are predominantly flat and dirt, utilizing an out-and-back structure on trails surrounding the park. A challenging hill near the finish offers views of the Flatirons and Front Range mountains. This event, now in its second decade, maintains a family-friendly atmosphere with post-race activities encouraging participants to bring guests.

Lucky Brew Race 5K, 10K, 15k & Half Marathon

Lucky Brew is a St. Patrick’s-themed race day on the Great Western Trail in Severance, Colorado, offering 5K, 10K, 15K, half marathon, and Kids Fun Run options. All distances start and finish at Severance Community Park, accommodating runners seeking an early-season test and families attending the shorter kids’ event. The 5K follows a 0.6-mile loop within Severance Park, while longer races extend beyond the park onto the trail. Finishers receive chip timing, photos, and a performance shirt. The post-race meal includes corned beef, cabbage, coffee, energy drinks, beer, seltzer, non-alcoholic drinks, and green beer from Peculier Brewing Company. Overall winners get custom clay mugs, age-group leaders receive gift cards, and half marathon finishers are awarded a medal. The event benefits the Great Western Trail Foundation and other local nonprofits, and it is one of four run.Windsor races qualifying for BOLDERBoulder.

All-Out Beat the Heat

All-Out Beat the Heat takes place in Westminster, Colorado, on the Big Dry Creek Trail near Standley Lake, offering 5K, 10K, and half marathon distances. This is the 15th year for the event, organized by All-Out Multicourse. It also functions as an official BOLDERBoulder qualifier, allowing runners aiming for a seeded start to achieve a qualifying time here. Each distance follows Big Dry Creek Trail southwest. The course is described by the organizer as having moderate terrain, neither excessively hilly nor completely flat. Half marathon participants experience the longest course, with sights of Standley Lake, the Front Range, and the Flatirons in the distance. The race benefits Adaptive Adventures, provides virtual 10K and half marathon options, and is part of All-Out’s Endless Series, alongside Fallfest.

The Colorado Marathon

The Colorado Marathon is a road race in Fort Collins, typically held on the first weekend of May. It includes a full marathon, half marathon, 10K, 5K, and a children's run. The full marathon begins early, attracting thousands of participants, ranging from local residents running shorter distances to marathoners aiming for a personal best or a Boston Marathon qualification. The marathon route follows the Poudre River Canyon for most of its distance before entering Fort Collins' natural areas and concluding in the city. This predominantly downhill course is a significant draw; in its initial four years, 18% of participants achieved a Boston Marathon qualifying time. Originally named the Fort Collins Old Town Marathon, the event maintains a local focus through charity entries, which are priced higher with proceeds directed to local charitable organizations.

Colorado 13er (Half Marathon/10k/5k)

The Colorado 13er begins at the Home Depot on Dillon Road in Louisville, Colorado, offering a 13.1-mile half marathon, a 10k, and a 5k on the same race morning. The half marathon starts at 6:30 AM MDT, with the 10k and 5k following at 6:40 AM MDT. Runners aged 14 and older are eligible to participate. The half marathon follows a loop through Louisville, featuring views of the Flatirons. Nine miles of the course consist of flat, crushed gravel, positioning it between trail running and road racing, distinct from a pure pavement event. The 13.1-mile course includes 10 water station stops and 5 portable toilet stops. All race distances are mechanically measured. Half marathon finishers will receive a 13.1 medal, and approximately 30 percent of participants report this as their first race.

About Half Marathon races in Fort Collins-Loveland

Fort Collins-Loveland Training Notes

Fort Collins-Loveland hosts 19 Half Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Locals run Fort Collins-Loveland from river path to foothill dirt. The Poudre River Trail gives runners 21 miles of paved path, and it often carries crushed gravel alongside it. 7 paved miles and meets the Poudre when base miles need to stay smooth. Spring Canyon Park has it all, with lines toward Pineridge natural area, Maxwell Natural Area, and Horsetooth. The route to Horsetooth covers 8 miles with a 656-foot incline. Fort Collins Running Club has kept the scene moving since 1971. Choice City Running Festival and Blue Sky Trail Marathon & Half Marathon sit on the local calendar.

Locals ride from Old Town Fort Collins toward foothills, prairie, gravel, and brewery laps. Fort Collins Cycling Club keeps the group-ride rhythm with A, B, C, and D pace categories plus Tuesday, Thursday, and Saturday rides. The route covers 6 km and 457 m of climbing as it swings around the southern end of Horsetooth Reservoir Overlook, rolls on to Masonville, descends into Loveland, and comes back by Cathy Fromme Prairie Natural Area. Fort Collins Northern Expanse Loop mixes 55% gravel with 45% pavement and dirt roads. Blue Sky Trail connects west of Horsetooth Reservoir toward Devil’s Backbone. Spring Dirt Pile Short Track at New Belgium Brewing brings the crit energy on dirt.

Spring and fall give runners and cyclists the cleanest training window here. The scorching heat of summer has given way in fall, and the chill of winter has yet to arrive. Fort Collins Cycling Club makes summer social with dinner rides in May, June, July, and August, while runners keep to shaded Poudre River Trail miles or move workouts earlier. Northern Colorado can feel windy and bright in exposed areas, so Z2 days need a little patience. Winter changes the rhythm more than the identity. The foothills near Fort Collins stay rideable much of the winter, and runners still have paved paths when singletrack needs time.
