Athleticism is more than dodging projectiles, wrangling mascots, and dropkicking a computer after it beats you in chess. Outfit yourself for adventure with today’s Groupon: for $20, you get $50 worth of sportswear at Whalebone Urban Surf Shop in Raleigh and at Whalebone Surf Shop in Nags Head and Virginia Beach.

Family-owned and operated since 1975, Whalebone Urban Surf Shop pays homage to sand and sun with swimsuits, sandals, and casual daywear from brands such as Billabong, Roxy, RCVA, Hurley, and Volcom. Glittering waves wet Quiksilver board shorts ($59.50) or L Space and Leilani mix-and-match bikinis, available in a rainbow of colors. In addition to beachwear, Whalebone Urban Surf buttons up Quiksilver Girl captain flannel tops ($49.50) that can be paired with Element Magic Sleeve jeans ($69.50). The summery white of O’Neill's frock ($39.50) complements Reef sandals such as the women's Ugandal 2 with thongs decorated in Ugandan paper beads ($42) to fit days that span from shore to sea-turtle-centennial celebration.
