This one's for you, San Francisco. If you're into swimming with the salmon, running across the Golden Gate Bridge, finishing on the field at AT&T Park, and hanging out after a run on Crissy Field on a warm October day - then get yourself eligible for the San Francisco Originals Run Series, back for its third year in 2015. It's a collaboration between San Francisco's most iconic running events, The Bay to Breakers, The San Francisco Marathon, The San Francisco Giant Race, and The Oral B Glide Floss Bridge to Bridge.

For those of you with the endurance to finish all four, we'll hand you a big fat SFO Series medal at the finish line of Bridge to Bridge.

How To Become A San Francisco Original:

1. Register for both the Bay to Breakers and SF Marathon by Friday, May 15th. Please use the same email address and name when registering. 

2. The first 2500 registrants will become eligible for the 2015 medal. 

3. Eligible participants will be notified by email the week after Bay to Breakers. 

4. You may run ANY DISTANCE in each of the four events to receive the medal.
