Aldi running socks are just wonderful, I'm totally in love with them - and they were a fraction of the price of my 'proper' running socks I bought with my trainers. I won't say I floated round W4R3 but I got there, and according to geodistance.com I covered 3.6km after the five minute warmup and before the warmdown walk. When I think I did W1R1 up and down the hallway and round the kitchen table at home I feel I've come quite a long way. Yet each run is still tough, it doesn't seem to get easier but it's do-able. I find it really weird how the first run of each session is so much harder than the rest, you'd think it would be easiest. Any advice for W5 would be much appreciated!
