We usually do varied pace for time not distance so the last two training sessions I've done was a pyramid hill session. 4x to closest lamp post, 3 x to next, 2x to nest and 1x to furthest then 2x next closest, 3x next cloest and 4 shortest one again. Each one is max effort up, recover down.
The interval training was 8 mins at 10k pace, 2 min recover (I jog/mum run), 4 min at 5k pace, 2 min recover, 2 min at max effort and repeated but in other direction as we do a loop!
The endurance workshop we did was similar but we did 5k pace, 3k pace and 1500m pace but slightly different times and only 1 min recovery but that was walking. The coaches say 5k pace is only being able to say one word at a time not a chat, that isn't my 5k pace but that's what I go with for training!
Parkrun test was good apart from them not being ready at 9! We had to stand around for about 10 mins and the start is quite narrow so felt a bit stuck behind some people for a while and that was with only 20 runners. I came 7th but haven't got a time yet, it's got a killer hill though :(
Good news about PB's 
I did 10K total today, a bit before park run and bit after. And I got some new trainers :) He filmed me and compared shoes and said three were all good, so I went with cheapest (was by £35). Apparently I overpronate in my leg, he said it could be that my break stops my foot rolling which is what stops it in the left! Also I needed 1/2 size bigger than I had and hopefully that will stop me getting a black toenail on my second toe of my right foot. Second toe is longer than big toe but my left one is the same length since I broke it!
