Pacing Smarter for Your Next Ultra with UltraPacer Founder Danny Murphy

How fast should you actually be moving at mile 20, 50 or 80 of an ultra? Danny Murphy is an ultrarunner, engineer and the founder of UltraPacer, a race-planning tool designed to account for the things that make trail racing complicated including elevation, terrain, altitude, heat, fatigue and even darkness. Scott and Danny talk about how UltraPacer started as a spreadsheet Danny built while preparing for his first 100K, why evenly pacing an ultramarathon usually isn't realistic, and how runners can use pacing data without becoming completely tied to a spreadsheet on race day. They also dig into race-day strategy, setting realistic goals, using training runs to test a race plan, and why a good pacing plan may be just as useful for your crew as it is for you.

Runners can account for variables including grade, terrain, altitude, heat, fatigue and darkness, then use those estimates to better understand what race day may look like. The majority of UltraPacer's features are available for free, and runners can use existing courses or upload their own GPX file to start building a plan.
