For this event any parkrun on any Saturday in September (and the first one in October) will count towards the competition. Your handicap time is based on your best performance over the handicap event distance (in this case 5K), or a similar distance, within the 12 months prior to the handicap event. For this event all handicap times will be calculated prior to 29th August. If, and we hope this is the case, you improve on your handicap time during September your original handicap time will still stand for the duration of the competition.
