This was my chance to run through the new 49ers stadium and practice field in santa clara and it was a great experience. The race is actually 4.9k to go in concert with the 49ers theme versus a traditional 5k. You get to run across the entire stadium all the way around, you see where they practice, park their cars and play. it was an incredible experience. The finish on the field was sweet! Since it was the start, the expo quality was okay. not too much to see. DO IT!!
