Are you running the Austin Marathon or Half Marathon this weekend?

Bring your bib to Cyc between Feb. 16-22 to get a free shake-out session. Ashley Landis for AAS

Cyc Fitness, an indoor cycling studio at 715 West 23rd Street, is offering a free class the week after the race to runners who show their bibs.

“We think of it as a fun, non-impact way for them to spin those legs out after the big race,” says Jessica Clark of Cyc.

I dropped in for a session led by Keoni Hudoba a few years ago, and couldn’t decide if I was at a fitness class or a nightclub. It’s a sweat slinging, music thumping experience that leaves you with a heavenly fitness hangover.
