With the London Marathon fast approaching, we thought we'd provide you with a look at the official Virgin Money London Marathon course route map! (Click on the map to enlarge.)
The Marathon (taking place on Sunday April 26) first goes through east London, then winds through central London, and finishes in Westminster, near Buckingham Palace.
If you're going down as a spectator on the day, there are plenty of options to get a brilliant view of the runners... And perhaps even see some famous faces!
Celebs including James Cracknell, Henry Holland, Greg James, Ellie Taylor and even Hugo and Proudlock from Made in Chelsea are said to be running this year, among many more. So get down and cheer on!
Here are our recommendations for where to watch.
Start of the race:
The London Marathon website suggests that watching the start point at Greenwich may not be a brilliant idea, as it can be uncomfortably busy, with a huge amount of people.
The Cutty Sark, however, just after the six mile point, is a popular vantage point with spectacular viewing points against a beautiful backdrop.
If you are tracking a certain runner, once spotting them at The Cutty Sark, you can then take the The Greenwich Foot Tunnel to the Isle of Dogs, where you can see the runners again as they approach the 17-mile point.
Middle of the race:
The iconic Tower Bridge is nearly at the halfway mark and is a brilliant place to watch the runners. Arrive early to grab a space here as it can be one of the most popular spots on the course.
If you're positioned near the Tower of London, you can also see athletes go over Tower Bridge, and then see them again as they pass on East Smithfield at the 22-mile mark onto Lower Thames Street.
Canary Wharf is also a popular and beautiful place to observe the runners as they double back on themselves.
If you're disabled or in a wheelchair, watching along The Highway is advised. It is not too busy during the day, and if watching the race between miles 13 and 14, you will be able to see the runners twice as the course doubles back on itself.
End of the race:
The last three miles of the race passes along the Embankment, turning right at Big Ben into Birdcage Walk and then past Buckingham Palace into The Mall to finish.
These are often incredibly busy spots, and crowds can get large. Arrive early, and perhaps go to Blackfriars and Waterloo Bridges to get an elevated view of the action.
St. James' Park can be a picturesque spot for spectators to watch the very end of the race.
Seating on The Mall is restricted to ticket holders; places are allocated in advance.
