Lara Bars have been a training and early race staple for years. Those bars have been gradually dying out for me. The only ones I can still do are blueberry, cherry, lemon, and lime. I usually can't stand them anymore past about mile 30. At Mohican, I grabbed a bottle of Ensure from my crew early (about mile 14) because I was feeling low on energy for whatever reason and ended up sticking to mostly liquid calories the whole rest of the race.
