I've run over 500 races pushing a disabled man ( my son ) in his wheelchair,
ok, before i started running with him, i was a highly expereinced marathon runner- but i've had, and still have loads of hurdles to overcome getting into races
i ve always sent our or my CV to race directors, - making it clear what ive done and in what time, making it clear i have little intention of getting stuck in the thick of thousands of runners - though its not that difficult
we run mostly at the back, using extreme caution, and work our way through, when gaps safely appear - or go from front, a few minutes ahead, then as the stretched out pack passes - they do so with safety
