Travel:
Public Transport: The Waterfront and Balboa maps are a short walk from downtown. Presidio is near to the Old Town Transit Center (a quick light rail ride from downtown). Vacation Isle and Mesa College are both a 4-5 mile bike ride from downtown or accessible via bus (#9, #44) from the Old Town Transit Center.
Parking: Free parking is available near to the start location on all maps. As Sunday morning's Waterfront race is in the heart of downtown, we recommend leaving extra time. Free parking is available in front of the County Administration building, we paid parking will be much easier.
Lodging: We recommend staying in the Gaslamp district near downtown for the full San Diego experience. Those on a budget or looking to minimize travels times should consider hotels in or near Mission Valley.

​
Questions:
What exactly is a "Chase" race? It's a race in which the fastest runner leaves first, with subsequent leaving based on their morning results. For example, if Jane won the morning race with Joe 22 second behind, she would leave at 10:00:00am with Joe leaving at 10:00:22am and so on. The first person to finish is the day's winner. Non-competitive runners will be started shortly after faster runners, on a 30 second interval.
Can beginners participate? Absolutely. While this is a competitive event with many advanced runners, urban sprint courses are great places for beginners to learn the basics in a fun, friendly environment.
Can I register for just one event? To maximize the competitive dynamic, participants must register for all events
together as a package. You don't have to participate in all races, but your overall results will be affected.
