Slateman Triathlon, 22nd May 2016 This was my third visit in three years to Llanberis, Snowdonia, to compete in the Iconic Slateman Triathlon, could i make it 3 wins in a row? The swim takes place in Lake Padarn in Llanberis. I was here a month ago with Raceforce/Always Aim High helping at a pre slateman training weekend. You can read more about this here The water was beyond freezing, it was Arctic. I wasn't massively keen to be jumping back into it this weekend. Wow, what a difference 3 weeks of sunshine can do, not exactly tropical but no ice to crack.
