Plan: right at the first T, turn at the 2nd T. 50 bar of penetration. #1 while swimming in. SAC 25 L/min. Everything was very relaxed and it was all fairly familiar terrain up to the first T. After the first T it all felt rather less familiar. Very good to do this properly together with Kim & Bas; you notice the streamlined communication. I could see two light beams neatly ahead of me. This felt very good. Team: Erik "Welcome to the darkside. (We got cookies!)"; Saskia "KB" Hoogmoed "And chocolate eggs!"
