Is it just me but those first 3 minutes were really tough today? My legs and feet felt like lead and I really struggled to keep going.
But come the last 3 minutes I was on a roll and managed to carry on running for another minute (and could have done more).
Is it normal to struggle so much in the first third/half?
My route is slightly uphill to start with and slightly downhill on the return but it feels like it's more than that.
Am kind of looking forward to week 4 but am also fearful of those interval runs
