Whole courseCrowdSix start waves from 5:30 am, set by the finish time on your applicationWaves A to F go between 05:30 and 05:57; the line closes at 06:05.

The organiser’s wave page reads: “Start Wave A: Finish time up to 01:50:00” and “Start Wave F: Finish time from 3:00:01 onwards and applications without a timing certificate.” Between them sit B (up to 2:10:00), C (up to 2:30:00), D (up to 2:45:00) and E (up to 3:00:00), all for a half marathon time. A marathon, 25 km or 10 km time is accepted too, with its own bands.

The handbook for the 2026 race gives the release times: A at 05:30, B at 05:33, C at 05:40, D at 05:47, E at 05:53 and F at 05:57, with the start line closing at 06:05. Official time runs from the moment you cross the start line, not from the gun.

Whole courseConditionsA cool start that is 28 to 30°C by 10 am5 am readings of 20 to 22°C, 28 to 30°C by 10 am.

The handbook tabulates the weather on 18 October for the past three years. At 5 am the readings are 21°C in 2025, 22°C in 2024 and 20°C in 2023, all clear. By 10 am they are 28°C, 30°C and 28°C, under a sunny sky.

The first wave goes at 05:30 and the last at 05:57. A runner in a late wave, or one who finishes close to the 09:40 cut-off, meets the warmer end of that range. The handbook’s own advice is to plan the early start and the travel to the stadium well in advance.

Three limits are stated and they are not the same thing. The handbook lists a “Finish cut-off time” of 09:40 on its race day timings. The wave page says that “timing results and certificates will be generated only for runners who complete the Half Marathon distance within 3 hr and 30 mins from the start time.” And the regulations say: “Course roads will reopen to vehicular traffic at 10:30 AM. Participants still on the course after this time must move to the footpaths to finish their run safely.”

A runner released at 05:57 in wave F has 3 hr 43 min to the 09:40 clock cut-off and 3 hr 30 min to an official time. The start line itself closes at 06:05, and a runner who starts after it gets no official time.

Whole courseFinishStart and finish at the stadium, on a measured 21.0975 kmThe finish line is inside the stadium; the course is AIMS-measured.

The information page gives “Race Starts from: Jawaharlal Nehru Stadium (JLNS)” and “Race Ends at: Jawaharlal Nehru Stadium (JLNS)”, with the distance as “21.097 Km approx.” The handbook adds that “your finish line is inside the JLN Stadium premises”.

The organiser also links the half marathon’s World Athletics and AIMS course measurement certificate. It reads 21.0975 km, grade A, measured on 11 October 2022 and valid to 31 December 2026.
