I completed the third run of week three this morning but found it absolutely knackering to reach the 3 minute mark however I did try to push myself on the last 3 minute run and like to think I managed 4 minutes (I don't carry a timing device) but man oh man am I feeling it now.
This is kinda putting me off starting W4 on Saturday and thinking I should perhaps squeeze another W3 run in on Saturday and start W4 when I feel more confident...
Or should I just throw caution to the wind and attempt it?
