We might not be experiencing arctic weather conditions, but its cold outside and thus fitting for the annual Polar Bear Metric Century - presented by the Rocky River Road Club - on Sat., Jan. 8. For cyclists looking to burn off any extra calories from the holidays or just show off some skilled bike speediness, this Lake Norman race is a must. And it's all for a good cause, as a portion of the proceeds will benefit the Ada Jenkins Center in Davidson. $20-$25. Registration at 8:30 a.m.; ride starts at 10 a.m. Ingersoll Rand, 800 Beaty St., Davidson. For more information, visit www.rockyriverroadclub.org.
