Jacek Mrukowicz Sets Second PR In Two Weeks

Jack Daniels Training Plan customer Jacek Mrukowicz set PRs in back to back weeks while following his marathon training plan. Last week he ran 40:41 in the Maniack 10k, almost two minutes faster than his previous best. This past weekend he ran the Warsaw Half Marathon 1:28:20, almost four minutes faster than his previous best and just ahead of what his plan had him scheduled to finish in.

With less than five weeks to go he’s well on pace to set a huge PR at the¬†Cracovia Marathon. Good luck, Jacek!
