The mercury dipped to just above zero as participants of Cupid’s Undie Run bravely stripped down to their skivvies.

Runners checked their coats — and their clothing — at the door of the Pourhouse to kick off the milelong run along Nicollet Mall in downtown Minneapolis.

Pre- and post-run parties for the third annual event were held at the Minneapolis party bar, which was decked out in Cupid-like pinks and reds. Funny, those were the same colors seen on the noses of many of the runners after their dash.

The racy, frozen run raised more than $70,000 to benefit the Children’s Tumor Foundation.
