Plan was about 7min/miles, so happy with the actual pace. Really want to keep all runs at or below 7min/mile now, even longer ones... 

No probs, but have got achey legs afterwards...

Was going to have a full week off as a decent rest (last 5 weeks averaged 10 miles per week) as my ankles/legs were getting a little sore, especially after my 8 mile run last Tuesday (2 miles of which was off road and pretty steep), and Saturdays ride had left my right knee quite tender when bending after not moving for a while, but Dan didnt need moving about at lunch today so I set off for a run with no particular plan. 

Started off fast so thought I'd do 4 milesish, but after 3 miles all under 7 mins I starting thinking about a 10k pb... I reckon half todays run was off pavement - mostly mown grass (football picthes) and park gravel paths, with maybe a mile on (mostly dry) mud trail - so not a typical road run, more 50/50 road / 'trail', which must have slowed me down a bit. - is a 6:45 min/mile 10k (42 mins) in reach?

Wore K2's - by far the longest run with these (previous probably being 5km runs) and after the run both feet/ankles (but especially the left one) are sore - not walking 100% right... not sure if its the shoes, the off-road trails, the speed, or a mix of all. My right knee wasnt painful at all while running.

Possibly 20 degrees, and sunny, so sweated a lot, with a hint of sore nipples after the run.
