The Monster Mash Dash is an un-timed and unsupported 3.1-mile fun run weaving throughout Oberlin beginning and ending in Tappan Square at the corner of Main and College. Wear your most creative, fabulous, or awkward Halloween costume! The best costume wins a special prize.

And, join us at Black River (15 S. Main St.) after the run for a Halloween afterparty!

Don't really like running? That is ok. You can walk, rollerblade, bike, or just hang out at the finish line and cheer us on. 

Reminder! Do not wear a racist Halloween costume. You will be immediately disqualified. Here is some guidance.
