Photos: Shivery sprinters in skivvies at the Denver Santa Speedo Dash

The holiday season brings all kinds of things out of the closet, from ugly sweaters to reindeer antlers. But at the Denver Santa Speedo Dash at Highland Square, little was left to the imagination as Speedo-clad runners in Santa hats raced through sub-zero temps to benefit the Life is Better Rescue pet rescue organization. Photographer Brandon Marshall was there to catch the near-naked, along with other runners in a gamut of costumes ranging from tutus and strategically placed gift bows to pajamas and gorilla suits.
