Ironman veteran and coach Mark Kleanthous will be online between 1pm and 2pm today to answer your questions about the ultimate triathlon distance: Ironman. Whether you're wondering if you have what it takes to complete this challenge, or you're already training for a long-distance triathlon this summer, Mark's here to help you reach the finish line with a flourish.
Mark is the veteran of more than 30 Ironmans and 400 triathlons. He has completed a triple Ironman and qualified twice for the World Championships in Hawaii. He has also somehow found the time to write a book - The Complete Book of Triathlon Training - which was published in February.
In addition to this encyclopaedic guide to our wonderful sport, he also helps other triathletes to acheive their goals through his website ironmate.co.uk.
We're opening the discussion now so Mark will be able to get stuck in straight away at 1pm (rather than having to deal with too many questions all at once). So get posting!
