So I've just done w5r2 (2 x 8 min runs with a walk of 5mins in between). I found at the 6/7min stage of the 1st run I was about ready to walk-fortunately a set of traffic lights came up very handily and it meant I could pause for a second and wait for them to change...I found the same thing in the 2nd 8minute run too although I pushed past this one and kept going. At the end I've never done the cool down walk so slowly in my whole time!!
My question is-do I repeat this run again...as there's no way I can do the 20mins (w5r3) as I did today. Or am I overthinking it and just try the 20minute run and repeat both next week if necessary??
