Notes
That first left turn was just insane, I think I lost a minute to it (which would have given me sub 7 pace overall). Then there was dodging slow people for about a mile. I think that the first mile was slow but tiring because I was trying to go fast only to be blocked every 30 seconds...
All that said, I think I had a bit more left in the tank that should have gotten used, maybe 25 even if I'd just pushed harder.
