5 to 6 is now my comfortable range,happy with that 2 or 3 times week.
Having said that we are doing a sponsored walk in July from Mynchlog-ddu to Rose Bush over the Preselli's which is 12 miles & one of the mothers of my U12's has asked me to run it with her rather than walk it.
Finish @ the Tafarn Sinc for a bit of light refreshment & we thought if we run,we get there sooner & have more drinking time 
Better pull my finger out a bit !
