A host of speedy triathletes ran the 2021 Virgin Money London Marathon on Sunday – here are the results.

It’s been a while – 889 days to be precise – since the last edition of the mass participation London Marathon. As always, plenty of familiar triathlon-related names, past and present, recording some pretty quick times around the capital city too. Here’s our attempt to highlight some of them.

No doubt we’ve missed a few (the event still in progress at time of first publication!), so do get in touch (editor@tri247.com) if you’ve spotted anyone we should add in. Don’t be shy – we really do appreciate your help!

This is a live work-in-progress and will be updated regularly as we spot and/or get updated on any notable names we’ve missed!
