Into Thin Air... Stayed an extra day in California to put some final pieces together, ahead of a busy few months on the road. Spent the day at the @guenergylabs HQ in Berkeley, testing, tweaking, and digging into the details with their performance team. It’s a privilege to have access to this space, and to the minds behind it. From fuelling strategies to altitude adaptation, we’re building a system around the demands of what’s coming in September — working closely with both GU and the @powerbreatheuk teams to dial in every detail 👌 More to come...
