London Marathon Race Day Tips: What to Know Before You Run or Watch
When it comes to the London Marathon, one of the world’s largest and most iconic annual footraces, held every April through the heart of London. Also known as Virgin Money London Marathon, it draws over 40,000 runners and nearly a million spectators each year, turning the city into a living festival of grit, cheer, and endurance. Whether you’re lacing up to run or standing on the pavement to cheer, race day isn’t just about speed—it’s about planning, patience, and knowing where to be when.
The London Marathon route, a 26.2-mile stretch from Greenwich Park to The Mall, passing landmarks like Tower Bridge, the Tower of London, and Buckingham Palace. Also known as Marathon course, it’s designed to showcase the city, but that also means heavy crowds, road closures, and unpredictable weather. You’ll need to know the key checkpoints, public transport changes, and where the best viewing spots are—because you don’t want to miss the finish line because you got stuck on a delayed Tube. If you’re running, arrive early. The start zones fill up fast, and even if you’ve got a bib, you’ll still wait in line for bag drop, toilets, and warm-up space. Bring a trash bag to stay dry if it rains, and wear old shoes you don’t mind tossing after. No one cares if your socks are mismatched—what matters is you crossed the line.
For spectators, timing and location matter more than you think. The best views aren’t always the most crowded. Avoid the start in Greenwich unless you want to stand shoulder-to-shoulder for hours. Head to Tower Bridge around mile 10, or the final stretch along The Mall where the energy peaks. Bring snacks, water, and a portable chair if you can. Many runners will thank you with a smile—or even a high five—if you’re holding a sign with their name. And if you’re watching someone you know, don’t just shout their name. Say it clearly, wave something bright, and stand where they can see you from the road.
Public transport shuts down early and stays closed late. Plan your ride ahead. The Tube runs limited service, and many stations near the route close entirely. Buses reroute, and cycling paths turn into pedestrian zones. If you’re not driving (and you shouldn’t—parking is nearly impossible), use the TfL journey planner and know your exit point before you leave home. Some runners even get picked up by friends at designated drop zones near mile 20—check the official site for those locations.
Weather in April can swing from sunshine to rain in minutes. Layer up. Wear moisture-wicking clothes, not cotton. Carry a small towel and a ziplock bag for your phone. If you’re spectating, bring a raincoat and warm gloves. The cold hits harder when you’re standing still. And if you’re running? Don’t try to break a personal record on race day if you haven’t trained in the rain. Consistency beats speed here.
Behind every runner is a story—someone raising money for cancer, a veteran running for fallen comrades, a first-timer who trained on London’s pavements for six months. The marathon isn’t just a race. It’s a city-wide moment of connection. And whether you’re in the pack or on the sidelines, the best thing you can do is show up, stay safe, and be part of it. Below, you’ll find real tips from people who’ve done it—runners who made it through, spectators who found the perfect spot, and locals who know exactly where to avoid on race day.
