The hardest part of a winter race is often not the training. It is the registration window. India's biggest events close entries weeks or months before race day, and some categories open and close on the same day.
If you want to race between January and February 2027, the next three weeks matter. Here are four entries to lock in now, with the dates that count. Every date below comes from the organiser's own website.
Why the deadline comes first
Most runners pick a race, start training, and plan to register "next week". By then the category is often full. Big city races in India fill their places early, and the most popular categories can close the same day they open.
So turn the usual order around. Check the registration window first, book the entry, then build your training around race day. A confirmed bib is also the best motivation to get out of bed on a cold morning.
The four entries
1. Tata Mumbai Marathon 2027: full marathon
The 22nd edition of a World Athletics Gold Label race. Entry to the 42.195 km marathon is only against a timing certificate from an earlier race, and your latest and fastest certificate gets you a better start wave. If you already have a certificate, this is the deadline to watch most closely on the whole winter calendar.
Good for: runners with a recent half or full marathon finish who want India's biggest marathon.
2. Tata Mumbai Marathon 2027: Dream Run
A one-week window, so put a reminder in your phone today. The Dream Run lets you be part of the same morning as the elite field without needing a timing certificate. The Senior Citizens' Run (4.2 km) and the Champions with Disability Run (1.3 km) are open until 5 November 2026, or earlier if full.
Good for: first-timers, families, office groups and anyone who wants the Mumbai atmosphere without a long distance.
3. Freshworks Chennai Marathon 2027
The 15th edition, and the first big race of the new year. The 32K Twenty Miler is a useful option if you have run a half and want to go further without jumping straight to 42K. The minimum age is 16 for the 10K and 18 for the longer distances. The start and finish details are still to be updated on the official site, so check them before you book travel.
Good for: runners who want to start 2027 with a goal race, and half-marathoners ready to step up.
4. Guwahati International Marathon 2027
A brand-new race: the organisers call it the inaugural edition and Northeast India's first international marathon, run alongside the Brahmaputra. Registrations opened in August 2026. The official site does not list a closing date, but first editions can fill fast once word spreads, so don't leave it to January.
Good for: runners who want a new city, a first-edition medal and a reason to explore the Northeast.
Most runners don't miss a race because they weren't fit enough. They miss it because they waited too long to sign up. Book the entry first. Once your name is on the start list, the training stops being optional.Amit Daga, Founder and CEO, Feet and Pedals®
Your registration checklist
Keep your timing certificate ready. Save a PDF or screenshot of your best recent result on your phone. Several big races ask for it during registration, and hunting for it while the form is open wastes precious minutes.
Set two reminders. One the day before a window opens, and one three days before it closes. Popular categories rarely wait for the closing date.
Check the age rules. Each category has its own minimum age, and races count it on a fixed date. Read it before you pay.
Read the refund and transfer policy. Some races do not refund entries. Know the rules before you book, especially if you are also booking flights and hotels.
Count back from race day. A half marathon usually needs 10 to 12 weeks of steady build-up, and a full marathon more. If you are planning a big jump in training, check with your doctor first.
Which one should you pick?
Have a timing certificate? Mumbai's full marathon closes first. Do it now.
New to racing? The Dream Run in Mumbai or a 5K or 10K in Chennai or Guwahati is a friendly first start line.

Whatever you choose, always confirm dates, categories and cut-off times on the official event website before you pay or book travel. Organisers do sometimes change schedules.
