Announcement

2026 venue change: Due to permitting at our longtime venue, Louisville Community Park, this year's race is moving to Rogers Grove Park in Longmont, about 14 miles north, with all-new courses. Same date, same distances.

Event Overview

The 13th annual Louisville Trail Half Marathon, 10K and 5K heads to Rogers Grove Park in Longmont for 2026. All three courses are new: fast, mostly flat routes along the St. Vrain Greenway and through Golden Ponds Park, with lake views and the Front Range on the horizon. The finish line is still the same family friendly party, so bring the family and enjoy the morning with us!

There's some history behind our new home, too. Rogers Grove was home base for two Endurance Race Series events, the Longmont Trail Half & 10K and the Rogers Grove Trail Half & 10K, last held here about 10 years ago, before Aravaipa acquired the series. This year's courses are updated, but we're returning to the same staging area and drawing on the original routes, with a few improvements we think runners will appreciate. We're excited to bring this piece of local running history back to Longmont while keeping our November 14 race on the calendar.

Race entries are non-refundable and non-transferable. For other options, please check out our Race Withdrawal Policy.
