The Gran Fondo Isle of Man cycling festival will now take place on August 30.
The occasion sees four different cycling races take place, from the 85-mile Gran Fondo route on mainly closed roads through to the family-friendly Minisculo Fondo covering 1.5 miles in Mooragh Park in Ramsey.
A spokesperson for the event organisers says they continue to follow government advice to make sure the event remains safe for spectators, officials, competitors and their friends and families.
They add anyone who's already entered and can't make the new date can either be transferred to the 2021 schedule or receive a refund.
