Under Armour, a sponsor of the N.F.L. Scouting Combine for prospective players, invited fans to test themselves in the same drills at the Super Bowl N.F.L. Experience this year. Fans who ran the 40-yard "Run to Daylight" dash were timed, with the fastest daily participant awarded prizes. Participants wore R.F.I.D. bracelets to sign up for the activities, which allowed them to share their times on social media networks as well as enter a drawing for two tickets to the big game.
