Bear Brook Trail Races

About the race

For 2026, we have decided to remove the 10k race and will no longer name our longest race a Marathon. It will be called the Bear Brook Trail Ultramarathon going forward. We will continue to offer a Half Marathon distance which will be as accurate to 13.1 miles as we can get it. For the Ultra - We will be a little less upfront on the distance - it will likely change from year to year and will be anywhere from 50k to 100k.... We will release the course 1 month before the race date and the old phrase "“How many miles did your GPS get?" will still be in play. We are excited to once again share the absolute beauty of Bear Brook State park and all the trails it has to offer. From beautiful single track, to steep uphills, and of course, the magnificent blueberry fields, Bear Brook has so so much to offer no matter which of the race you choose. .Please note that this is a NO CUP race - we do not supply cups at the aid stations. None. You will need to supply your own water bottles/soft flasks, etc to re-fill along the course. We will not have anything for you to put water in at the aid stations. This is to keep all littering in the park to an absolute minimum and ensure that we can continue to work with the State in obtaining this permit. Please note we do not allow pets to run during the race with runners and crews/pacers are not allowed.

2026 Course

Continuing in 2026, The Bear Brook Trail Races will be a GPX only event. There will be minimal to no course markings. If you are not comfortable with this format, please do not sign up. Entrants will be required to download the course GPX and utilize that to navigate their way along the course. The GPX will be made available in advance of the Event and will be sent to all entrants. Please contact us directly if you have any questions. Thank you!

Cutoffs
