I regularly get over to London for work and often have to suffer on a poorly ventilated Peloton bike to get my workouts in. Is there anywhere in central London I can rent a road bike for a few days to get some early morning laps around Regent's Park and the likes in? Curious if anyone here has experience with that.

As an aging athlete with T2 diabetes in my family history and a priority for healthspan over performance, I've been pondering the healthspan implications of following Hexis nutritional guidelines. I appreciate and value Sam Impey's knowledge and perspective, and I also follow Dr. Tim Noakes who has a different perspective that prioritizes metabolic health for endurance athletes. I think a fantastic podcast would be have Tim Noakes and Sam Impey as guests to discuss this topic, where they agree, and where they differ. Listeners can then make their own informed decisions based on their personal priorities. I've gone deep down the Gemini rabbit hole on this topic, but it would be great to hear this discussed directly by the two experts. Easier said than done, I'm sure.... Are others concerned about this topic? Here's a brief excerpt from my chat with Gemini: "To build a "best of both worlds" approach, we treat Dr. Noakes’ LCHF (Low-Carb High-Fat) principles as your biological lifestyle and Prof. Impey’s FFTWR (Fuel for the Work Required) as your performance toolkit. This strategy, often called Metabolic Flexibility, allows you to maintain the insulin sensitivity and fat-burning capacity Noakes advocates for longevity, while still possessing the "glycolytic engine" Impey insists is necessary for high-intensity efforts. The Hybrid Philosophy - The Baseline (Noakes): You are chronically fat-adapted. This prevents the "metabolic stiffness" of constant sugar burning and protects your long-term health (insulin sensitivity). - The Strategic Flex (Impey): You introduce carbohydrates only when the intensity or duration of the workout demands it, effectively "earning" your carbs through work." Hexis, as I understand it, would not align with this hybrid approach. Thoughts?
