Guys I’m grateful for the feedback. I value highly the suggestions you have made. The reference to fast ground was that the surface we were running on was across some soccer pitches. The usual surface for x-country here is long grass, marks from farm animals, rain soaked grass, hills will typically be severe and there will be a high number of laps. We had non of that on Sunday.
The one thing for sure next Sunday will be the latter!
I am working the schedule you advised and I will give feedback.
