Hi all.
Sharon - I ran this in 2010 as my first half marathon and am back again this year. I was terrified of the hill in advance but it turned out to be fine. It is almost 2 miles long but it isn't steep so if you get yourself into a comfortable pace you will find you can get up it relatively comfortably. The pay-off at the top is that, barring a couple of short, sharp ones, the second half of the course is easier and faster.
