Heat across five editions of an ultracycling race
Which edition of the Madrid-Barcelona by Pedalma was the hottest, and where on the route does the heat hit? A comparison built from my own GPS files.
I help cycling teams, brands, race organisers and sports-tech companies answer their questions with data: how hard a stage is for each rider, whether a product claim holds, why riders abandon a race.

I’m Juanfran Garamendi. I hold a PhD in Computer Science & Mathematical Modelling and have spent 15+ years working in data science and applied mathematics, in academia and industry. I’m also an ultracyclist, and I founded velodata to bring the two together.
How hard each stage is for each rider, who to line up, and which equipment is really faster.
Whether a product claim holds, and how to design the test that proves it.
