Spectators are anyone entering the event who are not participating in the event. There is no spectator age limit. Kids 12 and under are free. Most UK venues will require anyone 13 or older to purchase a Spectator ticket to enter the event, check on the race's specific event page for pricing. Typically, the fee is £10 if purchased online prior to the event (please note online registration closes at 5pm local time on Thursday prior to the race), and £25 when purchased on race day.
Note: Anyone under age 18 (minor) must be accompanied by someone age 18 or older (chaperone) at all times at the event. Each chaperone can accompany up to 2 minors. A group of 10 minors would require a minimum of 5 adult chaperones.
