San Diego isn't just a beautiful place for the sunshine and beaches (and Anchorman!). It's also home to three of our favorite Bachelor Nation buddies: Bachelor Pad Season 1 power couple Kiptyn Locke and Tenley Molzahn, and The Bachelorette 6 "winner" Roberto Martinez. Not only are the three amigos easy on the eyes, they are always out and about supporting good causes.

Not too long ago, they were in Roberto's former adopted hometown of Charleston, S.C., for a charity baseball game. Now they are staying in Cali to show off their toned bods in the San Diego Triathlon Challenge.

Yesterday, Kiptyn tweeted, “Inspiration fuels action. @Roberto_M_Jr (bike) @TenleyMolzahn (run) & I (swim) fired up to support @CAFoundation SD Tri Challenge next wknd!”

The event will be held Sunday, October 221 in La Jolla, CA. According to the official site, the event has a unique "challenge distance" triathlon course consisting of a 1 mile swim, 44 mile bike and 10 mile run. "This one-of-a-kind event will change your life as athletes compete side by side with Ironman champions, world-class challenged athletes, celebrities and other enthusiasts while raising important funds for the Challenged Athletes Foundation (CAF). Money raised will help CAF provide individuals with physical challenges with the tools necessary to find success in sports — and in life."

Based on Kip's tweet, it sounds like he’ll be doing the one-mile swim, Ten is training for the 10-mile run and Hottie Dimples will put his quads to good use for a 44-mile bike ride. Impressive!

We wish them the best of luck — from way over here on the couch, eating Cheez-Its. Stay classy, San Diegans!
