Ex-cycling photographer here! Accreditation isn't really necessary unless he wants finish line/celebration shots tbh, and those are hardly portfolio material. He'll also be able to drive on the route in advance anyway because it's a rolling road closure for ToB rather than a full closure. Unlikely he'd get accreditation without shooting for a specific outlet, but a quick google gives you this:https://www.tourofbritain.co.uk/about/press/
