Executive Director 

Susie Murphy started riding mountain bikes in the early 1990's in order to follow her husband, Sean Murphy, who had taken up riding with their young daughter in a backpack. She just needed to keep on eye on them, but they soon discovered a family pastime that took them on many adventures. Some of their best times were camping at Sea Otter, traveling to races down in Baja, and going to 24 Hour races with all of their friends.


Susie's first race was in 1995 at Callaway Vineyards in Temecula.  She threw up in the first quarter mile and ended up coming in third. She won a Rock Shox hat!  Susie did her last race in 2005 and won the Am Cup Series Super D State Championship for women over 40 while her daughter won the same title for women under 18.  In between she entered a lot of sport division races in California, Arizona and Baja California and occasionally brought home some hardware. 


Susie has volunteered in the cycling community for many years with over 25 years with groups such as the San Diego County Bicycle Coalition, the Mountain Bike Assistance Unit at Cuyamaca Rancho State Park, Go Girl, the Trek Superstores Women's Team, Big Bear Women's Only Weekend and Girlz Gone Riding.  Now rides for her are a little slower (with a few lift rides thrown in), races few and far between, and bikepacking may be the new thing! 


Susie is thrilled to be the Executive Director of SDMBA, since late 2015. She finds meeting and learning from all the dedicated volunteers and land managers both locally and nationally amazing.  She learns new things every day about San Diego.  Susie gets to ride new trails and dream of even more as SDMBA works as a team to get things done to make mountain biking and trails better for everyone.

Communications and Marketing Coordinator

Alex Oleata is a San Diego local with a passion for everything outdoors. After graduating college he was gifted a hardtail mountain bike from his younger brother, and that's where it all began. What started as casual cross-country riding quickly bled into Downhill, BMX, and Dirt Jumping. He's been involved in the cycling industry for years and has a love for all bikes from fixed gears to full suspension. Alex is excited to help engage the community, tell the SDMBA story, and create memories as the Communications and Marketing Coordinator. When he's not riding on two wheels you'll find him camping, surfing, or climbing a mountain. He's a regular at the Sweetwater Bike Park, so if you see him out there say "Hi!"
