Galen says the break reinvigorated him as running was getting to be a grind. I do not think Galen will get either the American record or a gold medal. Galen does allude to track racing and wearing spikes as possibly being a bit risky with his Achilles. Galen overall sounds fairly mature in the interview. The interview also alludes to the Olympic Marathon being his 3rd marathon in a 10 month window if all goes well.
