Make it an active Bank Holiday Weekend...

Get your walking shoes on and explore some of the Capital’s less known historic areas with a tour of the ‘gateway to London’ along the Thames’s eastern section. Starting alongside the grandeur of Woolwich Royal Artillery Barracks (short walk from Elizabeth Line, DLR, & Overground) – we have a special 50km looped route which heads into the heart of the Capital – alongside the long standing 25km option taking in Greenwich – and a family friendly 10km option if you’re after something a bit shorter! Routes steeped in history with iconic sights, a lively warm up, full support all the way, and capped with a BBQ meal, bar & music at the finish – making for a wonderful end of summer celebration!

Heads through the Woolwich Tunnel, and north along the ‘Capital Ring’ & ‘Greenway’ to the Olympic Park. It’s down to the Thames via the Lee Valley Walk to Limehouse, past The Tower of London, through the City, and across the Thames at Waterloo Bridge.  Back along the Thames – southside – all the way past the Cutty Sark and a rest stop at the Old Naval College. Then along the Thames to the Greenwich Peninsular, past the O2, past the Thames Barrier, through Charlton, and back up to basecamp in Woolwich, where a big cheer, medal, glass of fizz, T shirts and BBQ meal await!

REST STOPS: every ~12.5km; Picnic Lunch at ~25km; Finishers BBQ meal.

From the basecamp start – it heads through the Woolwich Tunnel to Docklands. Along the Thames, through Canary Wharf & The Isle of Dogs. Back under the River via the Greenwich Foot Tunnel, past the Cutty Sark and a rest stop at the Old Naval College. Then along the Thames to the Greenwich Peninsular, past the O2, past the Thames Barrier, through Charlton, and back up to the basecamp in Woolwich, where a big cheer, medal, glass of fizz, T shirts and BBQ meal await!

REST STOPS: at ~12.5km Greenwich Naval College; & Finishers BBQ meal ~25km

From the Woolwich Barracks start – it’s down to the River Thames – and along to the Thames Barrier. It’s then through Maryon Wilson Animal Park & Charlton Park before heading back to our Woolwich basecamp – where a big cheer, medal, glass of fizz, T shirts and BBQ meal await!

Coloured arrows mark the routes, with distance markers, and a map in the App just in case. Our ‘Trek Masters’ are out & about to provide support, with a chip timing system enabling the Control Room (and friends / family) to monitor your start & finish times. We have medics the rest stop venues to deal with any aches / pains or blisters.

Coffee, tea & biscuits at the start

  • Rest stop en-route midway, with a full range of free snacks & drinks
  • Free hot meal back at the Woolwich finish line for all finishers
