  • Please be aware that there is a 6-hour cut off for the marathon. As a guideline, if you have not passed the 1/2 timing mat by 10:30 am (3 hours after the start), chances are you will not finish in 6 hours. Please make your decision to continue or not at that time. Should you decide not to continue, you can get an official time for the 1/2 marathon by letting the race official know you are not continuing. If you choose to continue and do not finish within the 6-hour time allotment, please be aware that there may not be race support past 1:30 pm.
