Unsuccessful Tempo Run !!!!!

Simply couldn't keep the pace!

Program
1.5k warm-up 6km @MT pace (i .e. 7:38m/k)
1.5k cool-down.

 

 

 

I set VP for the first time in ages, thinking there couldn't possibility be a problem with that pace......WRONG!

8:52;  8:36;  8:07;  8:12;  8:44;  8:54.........and I thought I was running really hard! What a big mistake!

I don't have an answer or an explanation for finishing so far behind Virtual Partner, but very disappointed and cross with myself.

Today : 9km
