You just spent Valentine's Day (and night) romancing your new main squeeze, and everything's going great.
But you don't really know somebody until you run around the city in your underwear with them. For a good cause, of course.
Enter: Cupid's Undie Run, a whole new way to spread some love on Valentine's Day weekend.
Before you get going, you'll need to recruit a team of runners, preferably some who aren't shy about showing a little skin, and who maybe know a thing or two about fundraising.
With incentives like VIP open bar on race day ($150-plus) and custom Timbuk2 backpacks ($1,000-plus), motivation to find donors for The Children's Tumor Foundation should take care of itself.
Come race day, you and your Valentine just need to pick your underwear off the floor, slip it on with your running shoes, and head out the door.
In between the pre-race festivities, the jog around Fenway in your Sox briefs, and more partying after it's over, you should have plenty of time to determine if she's really the one, or if she just looks great in hot pants and a sports bra.
Cupid never lies.
