If you’re unable to run, you can still transfer your number to another runner on the day of the race. To do so, the person running should take the original entrant’s entry pack (including number and timing chip) to the race desk before the race, and they’ll sort you out. The original entrant does not need to be present.
YOU MAY NOT RUN ON ANOTHER PERSON’S NUMBER WITHOUT TRANSFERRING IT. For safety and emergency reasons we need to know who is on the course, not who originally entered.
