About the Event

Join the Club!

It's officially race season! And the Ten Trails Active Club is back at it with our 4th annual 5k Summer Series! Having a baby girl isn't going to slow down this team! Our summer series is our claim to fame and is a great way to build new friendships with your fellow community members - all while getting active alongside a supportive group of individuals with their own set of unique fitness goals.

The series consists of seven bi-weekly races. You only need to register once to be eligible to run or walk in all seven races (you'll be assigned a race number for the entire season at check in) ... and registration is FREE! We encourage folks of all fitness levels, and of all communities to come out and join us! Each race will be hand-timed on an open course, and results of each race will be posted on our website within a few days following the race. Post-race snacks and water will be provided as usual, but we ask everyone to bring their own water bottles to help cut back on plastic cup usage. The course has not changed from the previous years - details can be found here: COURSE MAPS | TenTrailsActiveClub (or on the link further below on this page). Note that this is a 5k despite what your watch may record... it's a twisty course through the Ten Trails trails! 

As with previous years, we will have prize categories for our fastest runners and walkers, as well as categories for racers who show the most club spirit, go all out on the sprint segment, or show the most support for others throughout the season. So, anyone can win in this series! But you must compete in at least four of the seven races to be eligible for prizes. Awards will be presented at our End-of-Season Awards Potluck which will be hosted a few weeks after the last race.

Races will be held every other Wednesday on the following dates: June 17th, July 1st, July 15th, July 29th, Aug 12th, Aug 26th, Sep 9th. Check-in for each race will be held in Civic Park at 6:00pm. Race announcements will start promptly at 6:30pm, with the official start to immediately following. On the weeks that we do not race, we do have a group run from Civic Park at 6:30pm that we encourage everyone to join as well.🙂

We can't stress enough how fun these races are! So, come on out and see for yourself! 😀

 

Excited to see you all out there!

Sponsorship Note:

We (a very small group of individuals) love hosting these free events for the community and have no plans on stopping! With that said, we have no large or consistent sponsors - so these events are not free for us to host! If you are in a position to donate and help keep these events going in the future, we would greatly appreciate it. Donations can be made during registration or directly to Coach Dalty in person. Every contribution is much appreciated!

Pulse Brewed Coffee (owned by Coach Dalty) also contributes a portion of his sales to funding Ten Trails Active Club events, so if you'd like to try some great coffee, give Pulse Brewed a try! You won't be disappointed!
