Bumbi says that the culture of the team has changed a little bit since Chris Solinsky left the team because no one hammers hard like him anymore. Solinsky was running 120 mile weeks while training for the 5K.
Wasn't Solinsky running that same mileage before training for the marathon? I feel like he said that in an interview when he was training.
