Do the trails at Donald Park a favor – by running on them.

The Donald Park Trail Runs will be held at 9 a.m. Saturday, May 4, at Donald Park, 1945 Hwy. 92, Mount Horeb, with the proceeds being used for trail maintenance and repair at the park.

The event will feature two race distances, one a 5K and the other a 15K option, both of which will go through the prairie and involve some sand, hills and bridges.

Registration for the races prior to the day-of is $30, and will increase to $40 on May 4.

Event registration includes a commemorative pint glass from Sili Pint, and a cash prize will be given to runners if they break the record for each race within their gender classification.

There will be additional prizes for winners in their age group, as well as a raffle following the races that any of the runners can enter.

Registration and additional information is available online at donaldparktrailruns.com.
