wow this thread moves quick doesn`t it. thought i`d have another look in.
did me first 80% run today.
15min warm up
then the main session, (copied staright from fetch training log)
20min out along cycle path, turn around and repeat basically. 
Split Summary ====
1) - 1m - 6:14(6:14/m) - 145bpm avge - 159bpm max
2) - 1m - 5:59(5:59/m) - 161bpm avge - 165bpm max
3) - 1m - 6:04(6:04/m) - 161bpm avge - 165bpm max
4) - 1m - 6:16(6:16/m) - 161bpm avge - 166bpm max
5) - 1m - 6:20(6:20/m) - 161bpm avge - 164bpm max
6) - 1m - 6:21(6:21/m) - 160bpm avge - 164bpm max
7) - 0.43m - 2:47(6:23/m) - 158bpm avge - 160bpm max
17min jog home to warm down.
the 160bpm got me a slower heart rate towards end but not really worried because i know that will improve within weeks esp with all the 70% running to back it up.
enjoying training at the moment now my mileage is back up to pre marathon levels. 
didn`t have any idea what my splits were until got home to find they were actually pretty good in my opinion. would like to see consistent 6min/miling soon hopefully.
