ボルダー周辺の定期開催Half Marathonレース

毎週、毎月、または毎年繰り返し開催されるレース

Spooky Sprint - Denver

The Spooky Sprint - Denver is a Halloween-themed road race held annually at Chatfield State Park in Littleton, southwest of Denver. As part of the Bodies Race Series, it offers a family-friendly setup with options for a 5K, 10K, half marathon, or an untimed 1 Mile. Younger children have their own untimed dash. The in-person races feature chip timing with live results and awards, and a virtual option allows participants to run independently while still receiving event merchandise. The race course is a road race within Chatfield State Park, with distances from a 1-mile family option to a half marathon. The expected attendance is in the hundreds, suggesting a focus on local runners, families, first-time racers, and those seeking Halloween-themed fun, rather than a large-scale urban event. Registration includes a custom bib, a designer shirt, and a finisher medal, along with complimentary participant photos and post-race treats. Children aged 10 and under can participate in the dash for free without merchandise. The 5K and 10K events provide reduced pricing for participants aged 12 and under.

Castle Rock Trail Festival / liveBIG Run

Philip S. Miller Park and the Ridgeline Open Space in Castle Rock serve as the setting for this trail festival, challenging runners on Castle Rock's extensive ridgeline trail system. This event is an athletic gathering, combining serious trail pursuits with a strong community and family spirit. Runners will navigate the varied terrain of the ridgeline trail system, experiencing the natural contours of Philip S. Miller Park and Ridgeline Open Space. Beyond the main races, the liveBIG Family Adventure Run offers a dedicated family obstacle course for children ages 5 to 12, ensuring an engaging experience for younger participants and an inclusive atmosphere.

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.

Halloween Trick or Trot Run 5K/10K/13.1 DENVER/AURORA

Turkey Trails- Denver

Turkey Trails Denver is an annual Thanksgiving-themed running event in Denver offering a half marathon, 10K, 5K, 1 mile, and a Kid’s Dash. It accommodates various participants: adults can select a longer timed race, families can opt for a shorter distance, and children 10 and under have their own untimed dash. The half marathon, 10K, and 5K are chip-timed with live results. The 1 mile and Kid’s Dash are untimed. Registrations include a custom bib, designer shirt, and medal. The Kid’s Dash includes a youth-sized shirt and medal. Children can also run the dash for free without swag. The 5K and 10K have youth pricing for ages 12 and under. The finish area provides free photos and treats. A virtual option allows participation remotely while still receiving event gear.

Marathon At The MAC

Marathon At The MAC is a self-paced indoor marathon on the MAC walking track. Participants complete 26.2 miles on their own schedule by walking, jogging, or running a total of 208 laps. After each walk or run, participants report their lap count to the MAC front counter staff, so the marathon can be built up over multiple visits. Runners and walkers scan in with a MAC Walking Track Pass when they arrive, participants under 18 need an adult with them, and everyone who finishes the full distance receives a T-shirt.

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.

TURKEY TREK (13.1, 10k, 5k & 2k)

The Turkey Trek is a Thanksgiving race series held at Long Lake Regional Park in Arvada, offering four distances: a 13.1-mile Half Turkey, the 10k Turkey Trek, the 5k Turkey Trot, and the un-timed 2k Turkey Toddle. The 5k begins at 8:30 AM MST, with the half marathon starting at 8:40, the 10k at 9:00, and the 2k at 9:10. This staggered start accommodates runners and walkers of various abilities throughout the morning. The course ascends to a summit at the 3-mile point, featuring the Egg Nog Chug Challenge where participants can drink 5 ounces of eggnog for a chance to win a new pair of shoes. Following the exposed upper section, the path crosses a ridge for a mile before descending the mesa's east side. The route then transitions to a flatter straightaway with hay bales for the Hay Bale Hop Challenge. This clockwise loop returns to the park, and approximately one kilometer from the finish line, racers encounter the Fill Your Pie Hole Challenge, involving pumpkin pie before the final push. Half marathon finishers are awarded a mug.

Run Denver 'Mile High City' 5K/10K/13.1

Run Denver 'Mile High City' 5K/10K/13.1 is a local Denver running event offering 5K, 10K, and half marathon distances, taking place in late November. It functions more like a supported group run than a large race: each wave is limited to approximately 15 to 20 participants, both runners and walkers are accepted, and timing chips are not used. The atmosphere is intentionally relaxed. Bibs are distributed on race day, participant gifts are mailed out, and organizers can record times by bib number upon request. Waves begin in the morning and are filled sequentially, with a waitlist or virtual run offered once capacity is reached. Participants receive a shirt, medal, and entry into a virtual runner community; the virtual option also includes text-based coaching support prior to the run.

Thanksgiving Gobble Trot Run 5K/10K/13.1 DENVER/AURORA

The Thanksgiving Gobble Trot Run 5K/10K/13.1 is a Denver/Aurora holiday race series offering 5K, 10K, and half marathon distances. Organized by The Best Races, it centers on a Thanksgiving morning running tradition: participants can race, jog, or walk before the day shifts to stuffing and turkey. The event welcomes families, friends, and local runners, not exclusively competitive athletes. The core idea is to enjoy the outdoors with others, complete a manageable distance, and burn calories before the Thanksgiving meal.

ボルダーのHalf Marathonレースについて

ボルダーでのベースマイル

ボルダーでは、2026年に市中心部から80 km以内で46件のHalf Marathonレースが開催されます。今後の日程、定期シリーズ、近隣のその他のレースをまとめて確認できます。

ボルダーには150マイル以上のトレイルがあるから、地元民は同じコースを週に2回走ることなんてめったにないよ。Mesa TrailはChautauqua ParkからFlatironsの景色を眺めながら続いてて、往復するとハーフマラソンくらいの距離で、2,000 feet以上の獲得標高があるんだ。Mt. Sanitasは1.5マイル弱で1,300 feetも登るから、ごまかしがきかないね。South Boulder Creek TrailとかBobolink Trailは、のんびりZ2で走るのにぴったりだよ。Boulder Track Club、Elevate Run Club、Fleet Feet Boulder、Avanti Run Club、RISE Runningなんかが、グループランの予定をぎっしり埋めてくれてる。Bolder BOULDER 10K、2026 Dash & Dine 5k Run Series、Boulder Marathonが、この街の主要レースだね。

ボルダーのチャリ乗りは、家を出たらすぐにロード、グラベル、シングル、そしてベースマイルを稼げるんだ。Boulder Cycling Clubは火曜の夜はTwisted Pine Breweryから、木曜の夜はUpslope Breweryから、どっちも午後5:30にナイトライドをやってるよ。長い方は2 kmで500 mアップ。短い方は7 kmで275 m。クライムは5 kmで3,112 mの獲得標高があるよ。Wednesday Morning VeloとかValmont Short Track Seriesのおかげで、レースの足が鈍らないんだ。

6月から9月は、ロングランや安定したライド、涼しい夏の夜に最高の時期だね。Elevate Run Clubは夏の間、毎週土曜の午前7時からロングランをやってるし、地元の人たちは午後の暑さが本格化する前にZ2やインターバル、トレイルランを詰め込んでるよ。Boulder Cycling Clubのウィークリーライドは3月に再開するから、夏が本格的に来る前にロードとグラベルのシーズンが盛り上がる感じ。冬もね、全体的に見ればかなり穏やかなんだよ。自転車道は定期的に除雪されるし、みんなスノータイヤを履いたファットバイクで冬中走ってる。日陰の場所は晴れた日でも雪が残って凍ってる時があるから、地元民は凍結に気をつけながら走ってるよ。
