  Run or walk with purpose and help us take steps toward ending period poverty in Northern Colorado. Did you know that in the US 1 in 5 girls miss school because she does not have access to the products she needs when she has her period?

  Colorado Center on Law and Policy stated in their 2018 Self Sufficiency Standard for Colorado report, “Almost two out of three single mothers lack income adequate to meet their basic needs.” A new survey done by Justice Necessary, a non-profit out of Colorado Springs revealed that of 1,256 Colorado women 18-40 years old, 57% of these women struggle with affording period products. Yes, you read that right, 57%.

  Join the women of Colorado Rocky Mountain Chapter, Delta Sigma Theta Sorority Inc. and the Fort Collins Running Club for a family-friendly 5K that brings movement, mental health advocacy, and community impact together in one meaningful morning. Every step supports period poverty initiatives and breast health.

  Participants are encouraged to donate period products* or bring a gently used or new bra to support women and girls in NOCO. Your donation helps to ensure dignity and care for all.

  *Period products exclusive to:

  • Tampons

  • Maxi Pads

  100 Mile Relay Race

  Join miles.Beyond in celebrating the Poudre River Trail. This long-distance race takes you on a sprawling tour of Northern Colorado via the picturesque Poudre River Trail. You'll enjoy scenic views and local amenities through Fort Collins, Timnath, Windsor and Greeley.

  While ultra distances can be daunting, this race is an ideal option for beginners and seasoned-athletes alike. With a fully supported course, great aid stations and abundant exchange zones this truly epic journey makes for an unforgettable running experience.

  The 50 mile race is point-to-point run. Starting in Bellvue at Watson Lake on Sunday morning runners will travel through Fort Collins, Timnath and Windsor to complete their journey in Greeley.

  The 100 mile race is a unique blend of an in person and virtual event: Participants will run 50 miles on Sunday, with the 50 Mile distance race, and complete the other 50 miles on their own within the seven day span of the event. The "virtual" miles can be completed on the Poudre Trail or any other location of your choosing, with results being submitted through the race website. Once the in person and on-your-own miles have been completed, you'll receive your 100 Mile belt buckle in the mail.

  Our post race party is waiting for all finishers in Greeley. Celebrate your epic race accomplishment with food, snacks, drinks as well as multiple cold plunges and recovery areas! Podium awards will be waiting for the top runners and teams.

  We're excited to share this journey with you and be a part of the newly completed Poudre River Trail spanning through many beautiful areas in Northern Colorado...the place we call home.

  Welcome to the 53rd running of the Horsetooth Half Marathon, Presented by Fort Collins Connexion. Your race will take you on a scenic point-to-point journey from the location of Hughes Stadium, the former home of the CSU Rams, to the finish line party at New Belgium Brewery. On the way you'll tackle the challenging hills of Centennial Drive along the shorelines of the shimmering Horsetooth Reservoir, before you head for the famed New Belgium Finish Line Party on the downhill Poudre River recreation trail. Whether an elite runner or a first time half marathoner, the Horsetooth Half Marathon offers a challenging yet surprisingly fast course, with a net loss in elevation.
