Ready to take on the three toughest challenges?
We are talking about the TCS London Marathon, the RideLondon 100, and the two-mile distance at Swim Serpentine. And in 2025, riders can substitute RideLondon for the 2025 Etape Loch Ness as part of their London Classics.
You can complete all three events in any order over any time period.
So if you ran the London Marathon back in the Nineties and only got into long-distance cycling at RideLondon 100 recently, you’d still qualify for the London Classics if you took the plunge and swam two miles at Swim Serpentine this year.
Whichever order you conquer your Classics in, the third event you complete will be extra special, as London Classics participants are awarded their medals in a special area after the finish of their final event.
You must also be aged 18 or over to take part in any of the events.
