From the San Dimas Stage Race organization:
"The San Dimas Stage Race (SDSR) organization is searching for families in the San Dimas area who would like to host riders for the 2013 race! Host housing is needed for the professional men's and women's bicycle racing teams competing at the 2013 San Dimas Stage Race - an opportunity for families in the area to connect with National Champions, Olympians, future Olympians, and hard-working racers striving to fulfill dreams in professional bike racing. The race runs from March 22-24 but teams typically arrive 1-2 days before the race and usually leave the day after the race.
SDSR is in search of families who live within a 30-minute maximum drive of San Dimas, CA. Opportunities exist to host men's and women's teams. See the SDSR website for race information. Host homes need to provide: a bed space (couch or air mattress is fine) for each rider, kitchen privileges, and refrigerator space; garage or other safekeeping space for bicycles. Host homes ARE NOT expected to provide: transportation or food - the teams will provide their own transportation and meals. Some families do like to provide some shared meals, but are not expected to do so.
Host families are encouraged to engage with their guest racers, as experience shows that involved host families find the experience most rewarding when they connect with their guests. Come watch them race, talk to them, find out what the life of a professional road cyclist is all about. If you would like to host a cycling team, please send an email to HostHousing@sdsr.info with the following information: Name, address, city, phone, email, and the number of riders you can host. Whether you can host one or two riders, or whether you and your neighbors can host a full team of eight, they want to hear from you."
I briefly talked with a woman last year who, with her husband, had hosted racers for a number of the past years, and spoke very enthusiastically about the experience. If this is something that sounds interesting, or you would like more information before making a decision, go ahead and contact the SDSR housing coordinator at the address above.
