In most dog sled races, the sleds must meet specific age and safety regulations, but there isn't a universal age requirement for the sleds themselves. Generally, sleds are expected to be in good condition, often less than a few years old, to ensure safety and performance. However, the exact rules can vary by race, so it's always best to check the specific regulations of the event.
