Nice footage, I always think the pan shot while running along side the runners is the most effective, yet so few people do it. At any rate, good luck in Chicago, as I think you mentioned you are doing it.
Chicago is next for me as well .. this was a great footage for sure; I love every bit of running in Boston was my first.. won’t be my last already qualified for next year at sub3 jk me - thank you anyways this was a tough course for sure
