As Bill Bowerman, legendary University of Oregon Track Coach, 1972 US Olympic Team Coach and Co-Founder of Nike said: The Williams Pace Calculator “is one of the most valuable tools any coach or serious runner can have”.

Accurate, individually tailored pace calculation is the critical component of intelligent, productive training for runners.

TRACK MODE provides immediate time and distance pace verification with accurate split times from 100M through 10,000M in 400M increments. Time increments as tight as 0.2 of a second enable coaches to verify individual training paces for distances such as the 100, 200, 300, 400, 500, 600 meters. Split times are available by simply sliding the scale and pressing the Calculate button.

ROAD MODE provides split times for Kilometers and Miles for distances from 10,000M through the Marathon by simply setting the target pace times for each distance. The Williams Pace Calculator has been endorsed and adopted by thousands of coaches over the years in its analog form. The new digital version of the Williams Pace Calculator makes the same customization for individual training available through your iPhone.

The Williams Pace Caculator

I have one in every car, one on my desk at work, one at home and now one on my phone. I don’t know how anyone can coach without this tool.
