Entering the Vedanta Delhi Half Marathon

Entry fees, closing dates and start times are set by the organiser and change every year, so they are not reproduced here — a stale deadline is worse than none. The organiser’s own site and its social channels are the authoritative source for the current year, and are where entry opens.

How to prepare for the Vedanta Delhi Half Marathon

How long to train

Build for 12 to 14 weeks from a base you already hold rather than from nothing. For half marathon the block should peak at a longest run of 18–20 km, reached at least two weeks before race day so there is time to taper. Ten days of reduced volume is enough of a taper at this distance; keep one short session at race pace in the final week.

Training for this course

The course is flat, which means no downhill sections to give your legs a break — you hold one rhythm the whole way. Train on similarly flat ground so the repetitive loading is not a surprise, and practise holding goal pace for long stretches rather than surging.

Conditions in October

Expect heat: daily highs average 31.9°C in October. Heat acclimatisation takes ten to fourteen days, so move some sessions to the warmest part of the day in the fortnight beforehand. Start slower than goal pace, drink to thirst at every station, and accept that a hot race is worth several minutes over a cool one.

Fuelling

A half marathon needs one gel or its equivalent around the hour mark for most runners, and a normal breakfast two to three hours before the start. Practise the same timing in at least three long runs so race morning is a repeat, not an experiment.

Race week

Sleep matters most two nights before, not the night before, so protect that one. Keep eating normally with a modest tilt toward carbohydrate, lay out kit the night before, and do nothing new: no new shoes, no new breakfast, no new socks. Plan to arrive at the start with time to spare — half marathon fields move slowly through bag drop and security.
