Runners looking for one last challenge for the summer get a bit of incentive with the final race of the West Deptford Park Summer 5K Series.

When they take to the cross-country course in the sixth race of the season, it won't just be glory on the line—the organizers have added the bonus of $50 gift certificates to the Haddonfield Running Company for the fastest male and female finishers.

The cross-country course is the same route the West Deptford High School runners brave during the season, which loops through the woods and fields around the park, challenging runners with constant elevation and terrain changes.

Registration for the race, which is $6 for adults and $4 for anyone under 18, opens at 6:15 p.m., with the start gun at 7 p.m.
