I went for a harder and a bit longer run today doing as much up hill running as flat trail runs although nothing is actually very level around Saltair it seems , I am slowly building up  my mileage and I'm gradually doing harder runs always trying to do as much trail running as road running, not pushing myself keeping an even pace with a slight lean forward and not extending my legs to far past my body, as I move forward, So far every thing is going good.
