Fueling Greatness: Andy Fior-Berry Runs 4th Fastest Bob Graham Round with BiCarrb

At FLYCARB, we love supporting athletes chasing the limits — and this past weekend, Andy Fior-Berry did just that.

Completing the legendary Bob Graham Round in a jaw-dropping 13 hours and 35 minutes, Andy clocked the 4th fastest time ever recorded on the iconic Lake District route. He now stands shoulder to shoulder with a handful of all-time greats, including Kilian Jornet, Billy Bland, and Jack Kuenzle — legends of fell running.

What Is the Bob Graham Round?

For the uninitiated, the Bob Graham Round is no ordinary ultramarathon. It's a brutal test of strength, resilience, and navigation set in the Lake District. Over 66 miles the route covers 42 fells and over 27,000 feet (8,200m) of elevation gain. Mortals aim to complete this in under 24 hours, but Andy went around in nearly half the time!

Fueling the Performance: How BICARRB Supports Ultra-Endurance Athletes

Andy used BICARRB to help fuel this historic effort — and here's how it can help with going deeper, faster, and longer in the mountains.

  • Lactate Buffering: In a race where steep climbs and fast descents flood the legs with lactate, BiCarrb can help delay muscular fatigue and keep Andy moving efficiently hour after hour.
  • High Sodium Content: With over 27,000ft of climbing, proper hydration and electrolyte balance are critical. BiCarrb’s sodium profile can helpmanage hydration and reduce the risk of cramping, especially under exertion in warmer conditions.
  • Stomach-Friendly Formula: Unlike many endurance supplements, BiCarrb is designed to sit comfortably in the stomach — allowing Andy to continue fuelling throughout the day.

If you're an ultrarunner looking to take on a mountain, a round, or an ultra of your own and you want the same BiCarrb boost then head over to our shop to get your fuel.
