Tips for walking a marathon
- Start at a conversational pace and settle into a rhythm; most people naturally walk around 100–120 steps per minute.
- Plan water and fuel for anything over about 90 minutes.
- Walking a race? Check the course cut-off time. The run-walk calculator shows how adding short running intervals speeds you up.
