I just bought a bike today, and we start fasting tomorrow! Was also thinking of doing a couple of kays between Asr and Maghrib (for non-Muslims - thats rights before we can eat in the evening). I figure it would be alot better to cycle rather than to run at that time (taking the easy way out!). I find that if I do anything strenuous in the morning, I feel lethargic for the entire day, whereas with the evening you know how much you have in the tank, so you can 'budget' your training accordingly. Ramadaan mubarak!
