This is not a race. It’s more like a series of fun runs, sponsored by The Brunswick-Topsham Land Trust and running, pun intended, once monthly through September – every second Thursday. You’ll get to explore the trail systems along the Cathance River, catch some views and maybe make a few new running buddies.

The runs will leave the parking lot at the new Head of Tide Park – be prompt, the group warns, it won’t wait for stragglers – and then meet up again after about a mile. You can head back to the parking lot then or continue on for another mile or so in a total loop of between 3 and 4 miles. Leave your dog at home and prepare for mosquitoes and ticks. The runs will be staffed by a couple of people with cell phones for emergencies. They’d love it if you’d carpool because the lot is small. Unless there’s thunder and lightning, they’ll run rain or shine. — MARY POLS
