Winning the overall amateur division by more than 10 minutes and placing 22nd overall. Dan thrives on continuous learning and being on the cutting edge of applied sports science. He often throws himself into the depths of new science, measurements and self-quantification to find out first-hand the effects that they have on training adaptation. --- Connect with the podcast on Instagram @isnpodcast and on Facebook @insidesportsnutrition This episode is brought to you by All Around Snack Co. which features tasty snacks that are low in added sugars, contain zero dyes, colorings or additives and help control blood sugar for steady energy levels throughout the day.  Use code ISNPODCAST24 to save 15% on your purchase.
