Northeast India and Kerala are quickly becoming must-run destinations for marathoners in 2026. Forget the scorching heat of North India – these regions offer cooler (or at least more humid-but-scenic) vibes, stunning backdrops like Brahmaputra riverbanks in Assam, misty tea estates and high-altitude challenges in Arunachal, and Kerala’s iconic backwaters, beaches, and hills.
Why run here? Lower crowds than big-city events, cultural immersion (temples in Palakkad, Buddhist sites in Tawang), tourism perks, and growing AIMS-certified races that attract serious runners. Whether you’re chasing a full marathon PB, your first half, or just a fun 10K, 2026 has solid options starting from late March onward.
Note: All dates and details are based on official announcements as of March 2026. This list focuses on upcoming events only (post-March 12, 2026)—past ones like February races have been excluded for clarity. Events can shift – always verify on the official website or registration page. For the complete India-wide list, check our Upcoming Marathons India 2026 Calendar.

Training Tips for Northeast & Kerala Marathons
These regions bring unique challenges: high humidity (Kerala especially), occasional hills (Tawang/Attappadi), and heat even in “cooler” months.
Region-Specific Prep:
- Humidity & Heat: Acclimate with early morning runs in Greater Noida-like conditions. Focus on hydration – check our upcoming guide on Best Electrolyte Powders & Drinks for Runners in India 2026 (Hot Weather Tested).
- Altitude (Tawang): Arrive 5–7 days early if possible. Train with incline treadmill or local hills.
- Hilly Terrain (Arunachal/Kerala trails): Add strength work (squats, lunges) and hill repeats.
Beginner 8–12 Week Plan Snippet (for Half/Full):
- Weeks 1–4: Build base – 3–4 easy runs/week (start 5K, add 10% distance weekly).
- Weeks 5–8: Long runs (up to 18–32K for full), speed intervals once/week.
- Weeks 9–12: Peak + taper – reduce volume last 2 weeks.
- Gear: Breathable shoes suited for wet/humid roads – see our Best Marathon Running Shoes India guide.
Nutrition/Recovery: Leverage South Indian staples – idli/dosa for carbs, coconut water natural electrolytes. Foam roll post-run to beat humidity fatigue.
