I'm into my 2nd week of your 6 week progamme, and it's brilliant -I love the variety, the structure, and learning a new form. 2 questions. The "running on hot coals" and the bare foot sessions, really help with forefoot strike... but when will my calves stop hurting? And I see what you're saying about the importance of high cadence, even at low speeds, but what changes when I want to go faster? I can't increase the cadence, I can't lengthen the stride... so what do I do?
