What are the wave start times?
The elite wheelchair race will start at 8.30am, with elite female runners beginning the course at 9.05am. Elite male runners will kick off at 9.35am, and from then onwards, the other waves of normies (and some famous faces, like Romesh Ranganathan and Alexandra Burke) will start their lap of the 26.2 mile long route.
