UPDATE: Top-4 things to know (Cut-offs)
Your start time, checkpoint deadlines and finish-line target — all in one place. Plan your day and know where you can request a shorter route. Finish within your race’s time limit to be recorded as an official finisher. The 10 km, 19 km and 30 km races have no intermediate cut-offs; their deadlines are at the finish. On a small screen, swipe tables sideways to see every column. Race names remain 10 / 19 / 30 / 46 / 80 km; the measured course distances are shown separately. Distances are cumulative from your race start. Elapsed time is measured from the start of your original race and includes all stops. The outward cut-off is 10:30 at 15 km. The existing race guidance cautions that arrival after 10:00 leaves little margin for later cut-offs unless you increase your pace. Assess your progress with the marshals; Djouce Wall at 23.9 km is the next opportunity to take the 46 km route. Speak to the marshals before taking a shorter route. A downgrade-request opening time is not a cut-off or an automatic entitlement to change course. Follow the marshals’ instructions. At 5 km · 19 km runners → 10 km 19 km runners may request a downgrade to the 10 km route here, but only after 11:30. At 9.4 km · 19 km / 30 km split Runners in the 30 km, 46 km and 80 km races may request the 19 km route here, but only after 11:30. Follow the marshals’ instructions. 80 km runners → 46 km If later cut-offs look out of reach, notify the checkpoint marshals and take the 46 km route as directed. Also notify the timing officials at the finish. You receive a finish time for the 46 km event but are not eligible for prizes. If you leave Sugarloaf at its cut-off, this is the time available to reach and leave Belmont. Leaving at the Belmont cut-off leaves 70 minutes to complete the final 7.3 km. Calculated from the 18:50 departure deadline, including any stops. Allow a margin for terrain and fatigue. This gives you 1h 30m for the final 7.3 km, rather than 1h 10m if you leave at the cut-off. Treat 18:50 as the last departure time, not your target.Know your limits.
