ROCKFORD, MICHIGAN - SEPTEMBER 21: Jeff Agar pedals his custom bicycle with his son, Johnny, in front of friend, training partner and fellow Ironman competitor Rebecca Cruttenden, on a hilly road named Egypt Valley on September 20, 2024 in Rockford, Michigan. On this day, the duo trained more than 35 miles with an elevation gain of 2,900 feet. "The full 112-mile bike ride in Kona has published elevation at 5,800, so the route we train on is really beneficial," Jeff Agar said. "Hills are our biggest nemesis. With nearly 400 pounds that we are carrying, I can feel an incline coming before I even see it." For 15 years, Jeff and his son Johnny Agar have been pushing the limits of endurance sports including Ironman triathlons. Their athletic accomplishments have been especially noteworthy considering that Johnny lives with cerebral palsy, a muscle disorder which necessitates assistance with his daily activities. When racing, Johnny receives full support by his sixty-one-year-old father to pull, haul and push him on course. In 2022, after five unsuccessful attempts, Team Agar completed a full Ironman - 140.6 miles of swimming, cycling, and running - within a 17-hour time limit. Nearly a decade after a failed attempt at the 2016 Ironman World Championship Triathlon in Kona, Team Agar was invited back to Hawaii to compete in this year's VinFast IRONMAN World Championship. Although the father-son-duo came up short of their dream of completing one of the most challenging triathlons in the world, they say their journey has never been solely about reaching the finish line. Their experiences have emphasized their commitment to overcoming challenges together as a family and connecting with those navigating disabilities and the struggles of everyday life.
