Fuelin Sessions

What does an Olympic champion eat when he’s racing for fun? Scott Tindal sits down with Jan Frodeno, Olympic gold medalist and three-time Ironman World Champion, to dig into how 100,000 lifetime kilometers and a bottle every 5K at 80 grams of carbs an hour added up to a 2:23 Berlin Marathon; why UTMB OCC a month earlier was the opposite story, with Jan running dry three times and drinking from a river; and how Scott is fueling the 80K Bondi to Manly Ultra he’s running for his son Jack.

Why do some athletes cramp no matter how much salt they take? In this episode of Fuelin Sessions, Scott Tindal is joined by Dr Alan McCubbin, sports dietitian and Monash University researcher, to work through the three main theories of exercise-associated muscle cramps. They dig into why the dehydration and electrolyte story has struggled to hold up in the research and how Kevin Miller's multifactorial model treats each athlete's cramps as their own recipe. Alan's take: there's no single cause, so control as many of the controllables as you can.

What do you do when you tear all three hamstrings off the bone and the first people you ask tell you it's probably just a strain? Scott Tindal sits down with Jen Harrison, a Chicago triathlon coach and lifelong swimmer who fell on a trail in Tucson, got sent home from the ER on crutches, and waited four days for the diagnosis. They cover the two to three week surgery window she nearly missed, why she shifted toward protein before the operation, how she ate through six weeks of bedrest, isometrics starting three days post-op, and the motto she taped to her desk: fuel for the season you're in.

In this episode, Scott Tindal sits down with Megan Foley, sports dietitian and professional triathlete, straight off her Nice 70.3 World Championship start. They go through the numbers day by day, why her fat dropped to 30g and her protein to 80g, the case for drinking your carbs instead of eating them, and the decision to front load 200g on the climb because the descent gave her nowhere to fuel.

Can a supplement get you sweating earlier and racing cooler? Scott Tindal sits down with Alistair Brownlee, the only male triathlete to win back-to-back Olympic gold, who now runs True Fuels and has just launched a taurine supplement called CoreCTRL. They discuss what the taurine and heat studies actually measured, whether a bigger sweat rate leaves you short on fluid, and how much of that effect a properly heat-acclimated athlete has already banked. Alistair also walks through the Kona blow-up that pushed him to strip race nutrition back.
