A working professional in Bengaluru went from couch to full marathon in 18 months. Here is what actually changed week-to-week, what hurt, and what surprised him about Indian running culture.

Most marathon training plans online assume Western infrastructure: cool weather, good shoes available, sidewalks. Indian runners adapt: Bengaluru runners do 4 AM long runs to beat traffic, Mumbai runners along Marine Drive at 5 AM, Delhi runners using cantonment areas to avoid pollution. The shift that mattered most: graduating from chasing pace to chasing time-on-feet. Once you can sustain 90 minutes of slow running, your marathon is mostly mental. The week 18 plan that crosses the finish line: 4 runs/week, one long (3-3.5 hour walk-run), three shorter (45-75 min), one rest day, one strength day. What surprised first-time Indian marathoners: race day fueling. Indian gut tolerates rice, banana, dates better than gels at km 25+. Test fuel strategy 6+ weeks before race day — race day is no time to experiment.
