I've had a blast at a social mountain bike race/relay the other week. Our corporate team wants to do it again next year, and in costume too.
Question is: Do you think these all-over costumes would work acceptably on an off-road bike race? I'm mostly concerned about visibility (the rider seeing out) and slightly worried about sweat and bunching.
Further details: Lap times were 30-35 minutes, so its not a sprint relay. The track was a mostly flat and dry singletrack with some shingle 4wd track. Downtime between laps was while 2x 3x 4x laptime, while other people did their lap.
