I know you've been looking for a reason to buy an ugly holiday sweater. Here it is!
Groupon currently has a $20 deal (normally $39) for the upcoming Ugly Sweater Run 5K here: http://www.groupon.com/deals/the-ugly-sweater-run-14?p=1
They describe the event as follows:
"The Ugly Sweater Run kicks off at 11 a.m. on Saturday, November 30, at NTC Park. Clad in their gaudiest holiday finery, runners chart an untimed 5K course fueled by hot chocolate before race officials dole out wacky awards. Each entry includes a custom vintage knit hat, unlimited hot chocolate, two hard ciders or lagers for runners age 21+, and a mustache; kids younger than 8 race for free. Each runner is encouraged to bring along a new toy to put under the race's huge Christmas tree and the haul is later donated to the local Toys for Tots chapter." All of that AND there's hot chocolate at the water stations!
Walkers are welcome, too! (I checked on the official website.) This will be a co-ed event.
