Race pace in haste?

As part of the Dublin marathon training and to increase overall speed we'll be adding in a few race pace training runs, and later we'll build in some fartlek sessions (I'll explain later). This 5 miler was very tough, especially as it is only a week since the Cork marathon. We ran it in 46:42, that's a pace of 9.20 and considering we ran a marathon last weekend that not bad!
