There's nothing more romantic than watching the sweat drip down your partner's face while you run through the University of Arizona campus trying to outpace dozens of other couples just like you.

The Fine Valentine's Couple's Relay, which takes place Sunday, has become a tradition over the past 17 years. This year's event benefits the Ben's Bells Project.

Hosted by the Southern Arizona Roadrunners, participants can opt for the four-mile Couple's Relay in which each partner runs two miles. The baton they pass will be a flower and there must be some form of PDA - Public Display of Affection. Prizes will be awarded for the best couple's costume.

Solo runners can sign up for a four-mile Ramp Run (that includes two sets of football stadium ramps). There's also a two-mile noncompetitive walk/jog to promote fitness (strollers welcome).

Longtime race organizer Randy Accetta this year passed the baton, so to speak, to new SAR board members Diane Manzini, Dari Duval and Alyssa Hoyt, who are all in their 20s. "This is their first program they've put on, and they are going to do a great job," Accetta said.

"We are trying to get more college kids and a younger crowd to participate in the race," Manzini said. "It is not a super-competitive race, so it fits well for planning our first race and for our personalities."
