Get Expert Guidance from Marathon Mentor Dennis Beggs

When you run with Team AFA, you’ll receive support from running mentor Dennis Beggs, a highly accomplished marathoner.

Dennis has completed 63 marathons, including all Six Major Marathons in less than a year, and most recently, he completed the World Marathon Challenge—running seven marathons on seven continents in just seven days. He is one of only 184 runners worldwide to achieve this remarkable feat.

As part of Team AFA, you’ll have the opportunity to meet virtually with Dennis for marathon advice, training tips, and motivation to help you reach your race day goals.
