Kristin, every rider/team deals with that in different ways. Some teams have paddler drop cyclist of at sac state, and drive up and park, so cyclist has ride back waiting for them. My rider hops on out to Coloma and takes it to Folsom blvd, which is directly to park access road, Rod Beaudry. (maybe 5 miles) Some also have peeps waiting for them, to give rides.
They also claim to not allow peeps into river bend access, but pretend you didn’t read that, and do as needed.
Hope that helps. Unfortunate EGR staff seem to ignore people interested in racing, especially with entry numbers down to what they are….
