When Run SMART client Don Strout signed up for private coaching his personal best for 10k was 54:54. This past weekend he lowered it once again to 46:36 at the Tour de Fleurs 10k in Dallas. This was Don’s 8th PR since he started working with Run SMART coach Vince Sherry last summer. To put Don’s progress into perspective he’s gone from around 4:19-4:20 marathon fitness to a potential of 3:32 in about a year.
