My third year at the TenTenTen, a tough little two-lap 10k in SW Sheffield.
Starting on grass for the first 0.5k through Endcliffe Park then a km of tarmac along the road until a short, sharp climb takes us up the the narrow, undulating, rocky, tree-root covered earth track through Bingham Park and Whiteley Woods. The first time around the large fled makes these crowded enough that the pace in constrained - at times even running two abreast is impossible - so when we crossed Porter Brook and got back onto the wider tarmac paths I decided to push the pace whenever I could.
This meant that my time for the first half wasn't far outside my 5k PB but when I hit that climb again I was feeling the run. The field had attenuated enough that the trail was less crowded so I had less excuse to ease off.
Back on the return leg I managed to keep a fast pace, down to 4:10/km, all the way around the tarmac and then the earth path on the North side of the park but, as we hit the last grass rise for the last few tens of metres, I couldn't quite speed my legs into a sprint.
Still, just snuck in under 45 minutes - 2 minutes outside my 10k PB, but this is not a course for PBs, so very pleased.
