Maybe keep them in for the first hour of your race, and then when you need the sports drink/GU gel, take them out and store them in a case inside a jacket pocket (not sure if it'll be cold enough for a jacket where you are...). That way you can cut the non-wearing time to 2.5 hours. Not super ideal, but it's better than risking cavities.
Good luck with the race!!!
