We love to receive email about our races, but please check the website for an answer before sending an email. We spend 5-10 hours responding to email each day, and 90 percent of the questions we are asked are answered on the race website. If you can't find an answer here, then definitely get in touch with us and we'll reply as soon as we can - typically within 24 hours!
