  1. Go-to
    Speed was the first Infinit product I tried; it got me hooked. The balance of electrolytes and carbs is so easy on the stomach and always leaves me feeling great. I use it during workouts over and hour up to around 3.5. Never any issues fantastic product!

  2. quick fuel
    I always alternate between this and the SPEED- for women. Not so sure what the difference is other than the flavor maybe but I love them both!

  3. Easy Fuel
    Speed works very well for my shorter more intense training rides. I use it for rides over an hour and up to 3-4 hours. I love how easy it is to get the carbs needed to sustain an intense ride without the need to use gels. Less to carry no waste. The flavor is just right not too strong or sweet.

  4. Speedy and Travel Ready
    This blend is the perfect blend for many of my vacation workouts. Generally shorter and ready to get after it. The single servings are great for travel as leaving a spare in the gym bag. This blend easily replaces my usual custom blends in a pinch and the lemon lime is always an easy go to flavor.

  6. Training Fuel
    I have been using Speed for most of my 2 hour or under workouts on the bike swim or run. Perfect blend of carbs and electrolytes. Speed has eliminated the cramping I was previously getting on my hour swims in the pool. I also used my Speed formulation this winter to set a 3 hour FKT on a 22 mile trail run. Five Stars. Check it out.

  7. Great for Intervals and shorter races
    I use this formula for interval days as well as shorter races and it works great! No bonk and no cramping! Plenty of energy to go the distance without having to carry any foot or salt tabs.

  8. Perfect for high intensity rides
    I use Speed for all training up to 3 hours and Crit races. It is easy on the stomach and tastes great! It helps me stay hydrated fueled and has reduced my calf cramps that would always flare up.

  9. All Purpose Fuel
    I love this stuff. Use it for running cycling and swimming. Go Custom for other flavors but we've used it for years and not changing any time soon.

  10. Go-to formula for short races!
    I use Speed for XC mtb races and it's fantastic! It keeps me fueled up when I'm giving it all I have in XC races! Excellent product that tastes great too!
