Brad has just completed an all-important test of his fluid tolerance, to see how far he's come. We also plan his upcoming nutrition dress rehearsal for Chicago.

If you're racing Chicago or Melbourne Marathons or another event in October or November you can follow along and apply the same principles to your own race nutrition preparations.

Back for its second season, T-12 is a brand new, unique podcast series that follows an athlete's journey as they prepare for race day. Over the final 12 weeks before the big event, we'll look at all aspects of race nutrition, from organising accomdation and race foods, to gut training and hydration, to eating during the taper and the day before the race.

A big thanks to Aid Station who have come on board to provide Brad with sports nutrition products to try in training, to assist with his race nutrition planning.
