I completed w2r3 this morning, but I don't feel ready to go on to w3. It's a real struggle (partially because there are a lot of hills around my house!), and I only just got through to the end of the sixth and final run. I also found that I'm getting dizzy towards the end of the fifth run, which makes the final one even harder. Does anyone have any advice? I find it slightly easier if I go in the early evening, but would like to figure out a way of making it doable in the mornings as well!
