SAN ANTONIO — Organizers of the Rock 'n' Roll San Antonio Marathon and 1/2 Marathon on Friday announced big changes to the event scheduled for December.

The seventh-annual installment of the run through the city will feature a second day of running, featuring a 10k.

The new Rock 'n' Roll Running Festival, sponsored by Humana, will kick off with the 10k, scheduled for Dec 6, the day before the marathon, 1/2 marathon, relay and 5k runs and bike tour Sunday.

The 10k will start at the Alamodome, run through downtown and wrap up at Alamo Plaza.

Those who complete the 10k and any distance race the next day will also receive a spinning “Remix Challenge” medal, bringing a possible tally to three medals throughout the weekend for participants.
