I am doing w3 second time through as I don't feel ready for that 5mins in w4. So far I've managed to run 3 of the 4 w3 runs relatively ok - Today was r5 and a complete disaster.
Humid, hot n sweaty. Felt I was struggling n tired. Fed up now
Will do another w3 run on Thursday but do I face w4 on Sunday?
How do you know when you are ready for the next step?
