A couple of years ago I was looking through a schedule that Jack had sent me to prepare for the Carlsbad 5k. The schedule was similar in format to what you would find in his book, Daniels’ Running Formula, but very different in terms of content. While I was looking at the schedule I wondered if most runners knew how many different schedules Jack had written over the years. At the time almost every competitive runner in Flagstaff (along with countless visiting athletes) had received a schedule from Jack for one race or another and no two were the same.
