Sport: Mountain Biking

I tried your products on the recommendo of a friend who is an aspiring pro mountain bike racer. I am a Master Expert class racer and have always had problems with proper intake of carbs during a race or long training ride due to an extremely high calorie utilization ratio. (Substrate Utilization) in medical speak. I tried Crank Sports e-Gel AND e-Fuel and with the ratios of complex to simple sugars and the larger sizes and overall convenience of use I am now a believer.I can’t wait to see my results this next race season with e-Fuel and e-Gel on my side. Thanks.
