The Chennai Marathon
A community-run marathon along a coastal city's flattest roads.
January
The month this race has traditionally been held in — not a date, and not this year's date. Chennai, 4 categories, run by Chennai Runners / The Chennai Marathon organising team.

What kind of race it is
Grown out of Chennai's own running community rather than a promoter's calendar, and it retains that character — strong volunteer support, an early start, and a field that knows each other. A well-regarded, unpretentious race.
The course
Flat. Chennai has almost no elevation to offer, and the course uses the coastal and arterial roads accordingly.
Conditions
A January date puts it in the coolest window Chennai has, but humidity is still the defining variable. Starts are early for good reason.
How to approach it
Flat and humid is a combination that flatters the first half and punishes the second. Run to heart rate or effort rather than pace after 25 km, and drink to a plan you have practised.
Distances offered
Category names and cut-off times vary between editions. The event is run by Chennai Runners / The Chennai Marathon organising team — find their official site for the current year's details, and cross-check against the AIMS race calendar. This page does not link to an organiser URL it cannot verify.

Free, complete, week-by-week plans — pick the one that matches what you can currently do, not what you would like to be able to do.
Training in Chennai
05:00–06:30. The beach at sunrise is the city's running ritual; by 08:00 the sand is already unpleasant.
