Paul Chelimo ran a 15.55 mile long run today. Not a race or anything. Just a regular long run. He ran it in 1:18:41. That's 5:04 pace. A half marathon at that pace is 1:06:22. Again, during a training run. This isn't a race or anything. He doesn't even have any races coming up within the next few weeks that I'm aware of.
He could run a 63 minute half right now. Not even in peak shape. Give him a few months to do some good mileage and marathon specific training and he can drop a 2:09 or better.
