Super helpful

I’ve never used gels on my run before and this app made me realize that it was a huge mistake. I followed this plan, started added gels and gained a ton of speed on my long runs. Great app

I’ve needed this!

So easy to set up and I can’t wait to start running with this. Really going to help me get through training for my races

Great Training Tool

Before Fuelstate, I would just guess how many gels to take on my training runs, but now I have personalized plans with the products I already have at home. Looking forward to continued training with fuelstate and ultimately using it on race day!

Cool app!

Really solid app! Haven’t seen anything on the App Store like it

Key for race day!

Amazing app! Very informative and user friendly. This is going to help so many runners feel more prepared for runs.
