The Chainwreck Cyclocross Series wrapped up with the fifth race Thursday at Tsalteshi Trails just outside of Soldotna.

In this cyclocross series, racers compete on a 1.5- to 2-mile course that includes obstacles forcing the riders to dismount and mount the bike. The leader does as many laps as possible in 30 minutes, and nobody starts another lap after the leader finishes.

Brian Beeson took the win with five laps in 31 minutes, 30 seconds, while Eric Thomason was second in 32:01. Morgan Aldridge was the top woman, and fifth overall, with five laps in 36:06.
