Thanks for your honest, positive words. Equally honest advice, based upon feedback from hundreds of Pro, World-Cup-class athletes: It's better to use SportLegs as part of your PRE-sports regimen. They work for recovery, too, but less well. Here's why. Formal randomized, double-blind placebo-controlled clinical trials have shown taking SportLegs an hour before helps elevate Lactate Threshold, the point where you run into the "burn", HUGELY. (We're doing more testing to corroborate eye-popping double-digit percentage gains.) It's like re-programming the rev-limiter chip in your car, if you're a modern drag-racer. Once you do that, though, you need more fuel; you need to anticipate higher nutrient flow rates. Long-term SportLegs users say that the higher "rev limit" encourages you to go harder, so you need to supply more conventional electrolytes- and hydration. So definitely keep the Cytomax or Accelerade handy. Just make sure you start the ball rolling with SportLegs.
FYI, this is info that 90% of 2004 U.S. National Team mountain bike racers know for sure, based on their own experience. Use it wisely.
