About us
We couldn't find fuel that worked for us.
So we started making our own for marathon training.
Tested it on every long run. Kept what worked.
That's how Tempo Fuel started.
Where it started
Here's a moment from the journey - figuring out fueling during marathon training, one experiment at a time.
Keerthi and I are DIY-ing our nutrition for marathon training this time around. We have been doing high mileage weeks (100K+), so nutrition has to be on point.

Lots of failed experiments last week, but we've made our own carb mix and it works great.
