From a recent interview:
Any regrets missing the U.S. Championships last month?
Yeah. It’s hard not being part of track nationals. My pulling out [of the 10,000m] was something of a last-minute decision. I trained for it and was excited to do it, but when Jerry and I made the decision to run a fall marathon, Jerry said that I needed to go out to altitude. I had already put a week in prior to that race [U.S. Track and Field Championships]. He just asked me, “What are your main goals for this year?” and I told him my main goal was to break 2:20, so he said, “then that comes at a cost of not doing USAs then.” I listen to Jerry. I fight certain battles, but for this one if my goal is a sub-2:20 marathon then that race was a casualty of it. It’s tough to watch other people compete. I was ready for it and I was excited to compete. It’s definitely something I don’t like to do, but he just felt like it was the right decision for my big goal.
