How a Basketball Icon Maintains Peak Fitness at 59

Reggie Miller's New Challenge: Mountain Biking at 59

Reggie Miller, a name synonymous with basketball greatness, has long been known for his incredible skills on the court. But after retiring from the NBA, he hasn't let his competitive spirit fade. Instead, he's found a new passion that keeps him active and engaged—mountain biking.

At 59 years old, Miller is preparing for one of the most demanding physical challenges of his life: the Life Time Tahoe Trail mountain bike race in Truckee, California. This 100K (62.1-mile) course features long climbs, fast descents, and high-altitude terrain. For Miller, this race is more than just an event; it's a testament to his commitment to health, performance, and pushing his physical limits.

Miller took up cycling after his NBA career, initially as a way to stay lean for his TV work. “I wanted to continue to look good in my suits,” he said. However, what started as a fitness routine quickly turned into something much deeper. “Once I started racing and those competitive juices came out—I missed that. I missed those butterflies from jump ball, the big shots in the moments, and the not knowing. That’s what cycling is about.”

A Deep Commitment to Fitness

Miller’s dedication to fitness is evident in his daily routine. He trains six days a week on the bike and lifts weights two to three times a week. His strength training focuses on power and durability, incorporating kettlebell swings, plyometrics, core training, and fast-twitch exercises. On days when he doubles up his workouts, he always starts with the bike before moving on to weightlifting.

Recovery and proper nutrition are equally important in Miller’s regimen. He carbo-loads with pastas or steak and potatoes before long rides and stays hydrated throughout the day. His hydration and fuel plan includes products like Maurten and Momentous, along with two protein shakes each day—one in the morning and one before bed.

“You've gotta get your recovery shakes back in you, that helps,” he explained. “It's all about body maintenance.”

Mental Toughness on the Trail

Training for endurance events requires more than just physical preparation—it demands mental resilience. Miller acknowledges that long rides can be mentally challenging. “Being on the bike and especially if you're on the bike long enough—it will take you to dark places. It will make you question things,” he said. “You will feel like you're seeing shadows and that the mountains are talking to you in some of these dark places.”

For Miller, this mental challenge is part of what makes mountain biking so rewarding. “That is why I love it, because as a former NBA player, you had to go to dark places. You had to think and play chess matches with your opponents. Now you're playing a chess match with your body and with the trail and with the canyons and the woods.”

Balancing Work and Training

Despite his busy broadcasting schedule, Miller continues to find ways to stay fit and focused on his training. When NBA playoff coverage limited his training window this year, he adjusted by shifting from long endurance sessions to short, high-intensity intervals. However, he admits that a race like the Life Time Tahoe Trail requires steady endurance rather than quick bursts of energy. He grades his training at around a B-minus, unsure how his body will respond on race day.

Still, his goal isn’t to win the race. Instead, it’s about showing up, staying committed, and testing his limits. “Once an athlete, always an athlete,” he said. “I'm racing to survive this race on Saturday, and to finish. So my main goal will be to finish.”

A New Drive for Adventure

Miller’s approach to fitness is simple but powerful: push hard, stay focused, and keep challenging yourself. “Once you retire—that's why some guys go to golf or tennis. Mine has been on two wheels, and that's what drives me,” he said. “Lining up with these other amazing athletes, men and women, as young as 13 or 14 and as old as 80, being able to conquer a 60-mile, 6, 7, 8-hour mountain bike ride, to be amongst those people—that's what kind of drives me now.”
