Running in Kolkata: A Local Runner's Guide
Kolkata's winter is genuinely pleasant for running, a short but reliable window bookended by a hot, humid year on either side. Most of the city's racing calendar is built to sit squarely inside that window rather than push its edges.
When is Kolkata's racing season?
Most Kolkata road races run between late November and January, when the city's brief but genuine winter brings cool, dry mornings. Outside this window, rising humidity and heat make outdoor racing considerably less comfortable, similar to the pattern seen in Chennai though slightly less extreme.
What Kolkata race courses tend to look like
Kolkata's major races typically route through the city's wide colonial-era boulevards and around Maidan, the large central park, giving a largely flat, straightforward profile. It's a reasonably good city for a first attempt at a distance or a time-focused goal, without significant elevation to plan around.
Popular training spots
Maidan is by far the most commonly used training ground in the city, a large green space with multiple loop options away from traffic. Rabindra Sarobar lake also hosts regular early-morning group runs, and the city's running clubs are active enough that joining a weekend session is a reliable way to pick up current local race information.
Planning a Kolkata race
Because Kolkata's comfortable window is short, races here are usually scheduled well within it rather than at its edges, so weather surprises are less common than in cities with a longer, more variable season. A standard race-week checklist applies without much need for city-specific adjustment beyond the usual basics.

My honest read is that runners here have learned to trust the season: because the comfortable window is short and well understood, there's less reason to wait and see how the weather looks before committing. It's a useful reminder that a narrower, more reliable season isn't necessarily a disadvantage for an organizer.
