Does anyone worry about the calories in the Cluster Dextrin? I'm trying to stay lean for the race.

Mike, for a Spartan, you’re going to burn 2000+ calories. 25-30g of carbs intra-workout is just fuel. It’s better than hitting the wall and failing an obstacle.

Exactly. Performance > Aesthetics when you're training for endurance. You can cut the carbs on your rest days if you're worried about the scale.

One last tip, Ed: test your mix during training, not on race day. You don't want to find out that a specific sweetener doesn't agree with you while you're 5 miles deep in the mud.

Smart move. I'll order some samples of Cluster Dextrin and Alpha-GPC today and start experimenting on my Saturday long runs.
