At 7:07/km, a 5-hour marathon is a steady, sustainable pace. The pace itself is very manageable — the genuine challenge is being on your feet for five hours. This is where hydration, nutrition, comfortable shoes, and mental strategies all become as important as your running fitness.
A sub-5 hour marathon is achievable with three runs per week totalling 25–40 km. The long run is your priority — build it to 25–28 km over the 16-week programme. The other runs should be 30–45 minutes of easy running.
A run-walk strategy works well at this level: run 10 minutes, walk 1 minute. This keeps your legs fresh and actually produces a faster overall time than running continuously and bonking at 30 km.
Practice everything in training that you'll do on race day: shoes, socks, clothing, nutrition, and hydration. Five hours is a long time to discover something is causing chafing or stomach issues. Body Glide and tested nutrition are your best friends.
