The most famous marathon in the world returns to its April slot today (Sunday) as 50,000 runners take to the streets of London.
Every vantage point in England's capital city will be packed with the spectators, willing to roar runners around the 26.2-mile course. But whilst hoards of spectators will take to the streets, millions more will be following from the comfort of their own homes.
The elite wheelchair men's and women's races will be first to get underway at 9:15am. The elite women's race will begin 10 minutes later, while the elite men's race and general public competition will start at 10am - lasting until around 4pm in the afternoon.
