How fast would someone like Mo Farah, Galen Rupp, Geb, Bekele, etc. run for a half marathon off 8 miles of easy/steady running per day and nothing more. Maybe occasionally throw in 3-4 faster miles on a run, but fairly easy running for the most part…going at a pace where a conversation could be held. No speed work and no more than 8 miles in a day. I ran a 1:13:50 half marathon off this training. Would they be able to break 1:05 off this? I want to know how untalented I am.
