So, a 5k ten days ago in 22:15. This gave a "projected" time of about 1h45 for the GNR yesterday. But I actually managed 1h55 and I think I was pretty much flat out (I wasn't zigzagging around too much). It was very warm but I don't think this would have affected my time so much (would it?).
So how to close the gap? I'm thinking the simple answer is... longer training runs. I mostly train only up to 10-15k. Is this the simple answer?
So I have a 5k on Friday and today I did my last training run (around 5k). As you do when you run, or as I do anyway, I pondered how much good it would do me.
If I missed this training session, how would my race time be affected? It must be affected, right? Or there would be no point doing it. Would my race be 1 second slower? 5 seconds? More? I know this is hard, maybe impossible, to answer, but the exercise makes my brain run out of control... Is there any rule of thumb?
