10 Mile Race

So I was not ready for the amount of hills that course presented me. Had a weird numbing(like pins and needles) in my left foot...felt like leg was peg leg but still had mobility..anyone know wha causes this? Almost wanted to give up at mile 4 but I kept pushing...my goal was 1:50 or under but no big deal. I am just glad I finished it. I know my half marathon in Disney will be a lot more FLAT. I guess it was good to get the hills in there though. I ran 11:12 minute miles finishing in 1:52:07
