Yesterday, I participated in a live chat previewing next weekend’s Scotiabank Toronto Waterfront Marathon. Among the participants were elite marathoners Reid Coolsaet, Dylan Wykes and Brandon Laan, who answered lots of questions about diet, warm-up, tapering and things like that. The most interesting nugget for me was some practical info about how to use beet juice: while I’ve blogged numerous times about the studies showing that beet juice provides a significant endurance boost, lab studies are very different from on-the-ground experience.
The most recent lab study used 500 mL of beet juice 2.5 hours before a time trial. But here’s what Reid had to say:
ReidCoolsaet: 500ml the day before. Anything the morning of upsets the stomach too much.
DylanW: Trent Stellingwerf has a protocol for 500ml in the 3 days before and 250ml morning of.
