I started running about six months ago in order to try and lose some weight. Well, I have been bitten by the bug and now try to run four times a week. My mileage is about 20 - 25 miles per week. I have always been a plodder, runnig at about 9 min miles. I have entered the Bristol Half Marathon, due in ten days and am having a crisis of confidence. I lost four weks training eralier in the year due to injury and so far my longest run has been 9 miles in 1 hour 25 mins. I feel I should try one more long run (11 miles) before being confident for the Bristol half. What should I do!!!
