Common Questions About Running a June 5K in Montana
How much does a June 5K cost to enter?
The typical entry is $20, with paid entries running from $10 up to $45. Entry fees climb as race day gets closer, so the same race is usually cheapest the week it opens.
What is a good 5K time?
Across the 5 of these June 5K races with published results from past editions, the median finisher ran 38:21, and the median winning time was 17:40. So anything under 38:21 puts you in the faster half of a typical field. That is the middle of these RunSignup fields, walkers and charity entrants included, not a national average.
How big is a typical June 5K field?
The median one finished 50 runners, across the 5 of these June 5K races with published results from past editions. Most are far smaller than the big-city events people picture, which means less crowding at the start and a friendlier field, with a last recorded finisher at 55:47.
Are there trail 5K races in Montana in June?
Yes, one race around Montana gets you off the pavement: 1 mixes road and trail. Surfaces are not always published, so it is worth checking a specific race before you register.
5K Races in Other Months
