The Siege Bouldering Competition

London’s Biggest Bouldering Competition

Cry ‘Havoc! The Siege is coming to unite London’s climbers in a city wide bouldering campaign.

Stand firm, for the walls will not break themselves.

Running from February 9th to March 4th across Climbing District London, this month‑long campaign summons climbers to test their endurance, cross each gym, and step into a shared tale of grit and ascent.

The road is long and the trials are fierce. Will you reach the finals?

Raise your courage, The Siege is upon us.

How to Join the Fight…

You storm Tottenham Hale, London Fields, and Bermondsey (Building One), taking on The Siege’s 25 blocs at each location. Your mission is to conquer as many as you can and build your score as the campaign unfolds.

Join the campaign whenever you choose, but to claim a shot at the finals, you must fight through at least two gyms. Only those who journey across the city, meet fresh walls, and show their strength on multiple fronts are called to the finals arena on the 7th of March!

Climb with intent.
Record every triumph.
Force your score upward.
Your road to the finals is cut in chalk and grit!

Entry to the Final Arena

Finals Day is the last stand of The Siege, the day the arena lights up, the crowd gathers and the campaign reaches its breaking point.

Spectator tickets are £5 inc. a Free Drink, giving you full access to the atmosphere of the arena: the battles, the noise, the tension and the final fight for the crown. Thy ticket also secures thy place in the raffle, whose top bounty is a two‑month membership.

If you earn your place in the finals, you’ll be invited to step into the arena and face the final set, no ticket needed. Your path is carved by your score.

If you want to come on the day, climb, soak up the energy or take on Best of the Rest, it’s normal entry at the desk. The gym becomes a living battlefield, open to anyone who wants to be part of the final chapter.

Stand with the crowd. Step into the chaos. Witness the end of The Siege.

The Way of the Siege…

  • Each gym unveils 25 blocs awaiting conquest
  • Log every victory to forge your campaign score
  • Move through the gyms in any order and climb as you choose, but remember all scores must be in by March 4th
  • Conquer blocs at two out of three gyms to earn your right to the finals
  • Those with the highest scores rise to the live finals and fight for the podium on March 7th at Tottenham Hale
  • Entry to The Siege is open to climbers aged 14 and above

The Rewards of the Victorious

The Siege grants its rewards to the worthy.

Podiums

  • 1st receives £200
  • 2nd receives £100
  • 3rd receives £50

A celebration of strength, strategy and persistence, the Finals podium honours the climbers who battled through every stage of the Siege

The Trial of the Best of the Rest

The Best of the Rest, a separate arena that opens alongside the finals, built for every climber who wants to stand in the fire of Finals Day. It is open to anyone, whether you battled through The Siege or are stepping into the story for the first time.

You face 25 blocs forged exclusively for this arena, with the chance to rise to the podium and seize the prizes awaiting the worthy.*

*Best of the Rest does not affect the finals results or the finals podium. It stands alone as its own contest, its own battlefield and its own chance to conquer. Separate and different prizes to the main event of The Siege.
