2021 UPDATES! The long-time race tradition is moving to Saturday with a limited field in-person half marathon road race. Enjoy a picturesque two-loop 13.1 mile course along the Farmington River and local farmlands that begins and ends in the center of Simsbury, a charming town center with quaint shops and great restaurants.

In-person half marathon participants will start in waves and race bibs will have official B-Tag timing. The event will be modified to adhere to social distancing guidelines with on-site support services provided, including packaged to-go snacks for all to enjoy after.

Not up for the half marathon distance? Find a buddy and take on the brand new 2-Person Relay! The race will follow the same course as the in-person UConn Health Half Marathon, with one exchange zone located exactly at the halfway mark! Each leg is exactly 6.55 miles.

Virtual race options include a 5K, 10K or half marathon and the return of the popular 3-distance Iron Horse Challenge (which can also be completed by in-person registrants!).

All participants receive a short sleeve technical shirt and a custom designed finisher medal to commemorate a great race.

Give Back: Please help give back to the community that has opened their streets for participants. Donations of nonperishable food will be collected on race day through the HMF Can drive to benefit Gifts of Love Food Bank in Avon.

There will be ten (10) start waves, starting 2 minutes apart between 7:30 AM and 7:50 AM. Each wave will have up to 75 registrants (updated April 2021), participants must provide their estimated finish time during registration to determine which start wave they’ll be in. Waves will be announced race week. After the race, participants pick up their finisher’s medal and enjoy a pre-packaged snack on the way back to their vehicles. Results will be posted online only at the conclusion of the event, times are based on chip time, there will be no gun time. Final results and divisions will be scored to include runners from all waves.

Submit your results through your haku participant account. Click here for more details.

Participants earn all of the same great swag, and will have it mailed to them after event.

Virtual race participants are urged not to run the official race course on Saturday morning (June 5); doing so will threaten capacity compliance and risk a breach of public health and safety requirements. Compliance by all will be necessary to support the safe return to in-person racing for future events.
