What is the minimum age to take part in a duathlon?

The minimum age to take part in a duathlon is 15 years on the day of the event?

Can I wear headphones at a duathlon?

No, hey are not permitted at any time.

Am I allowed to mark my spot in transition?

No, you are not allowed to mark your spot in transition, You must remember where your bike is. The end of each row will have the numbers in the range to help you identify where you are.

What do I need in transition?

The obvious answer is your bike. You are also permitted to take in a small rucksack with your belongings in. You must have your helmet and running shoes and if you are using them bike shoes.

How does transition work in a duathlon?

You have your own numbered spot in transition and you leave your bike here. When you run in to transition following run 1, get to your bike and before touching it put your helmet on and do it up. Once you have done this you can un rack your bike and run/walk to bike out. At bike out there will be a mount line (this will be signed and marshalled) and get on your bike. When you have completed your bike, come back to bike in (again this will be signed) and the dismount line, get off your bike and run/walk with your bike back to your spot. Once there, rack your bike and at this point you can unclip your helmet and take it off. From here you run/walk to run out to complete run 2.

Transition will be well signed and marshalled. Please fell free to ask marshals for advice.

How do I know where to rack my bike in transition?

There will be a spot in transition just for you. This will be numbered and will correspond to the race number you receive on the day.

Yes, you must wear a helmet at all times you are in contact with your bike.

Do I need a super duper bike to compete in this event?

No, as long as your bike is roadworthy any bike will do (someone once took part on a Penny Farthing). However, make sure it is safe for use.

Are dogs allowed at this event?

Yes, but they must be kept on leads and any mess cleared up.
