The NSPCC Gherkin Challenge

This charity fundraiser for the NSPCC returns for 2015 and requires participants to run up the 38 flights of stairs of the Gherkin either individually or as a team. The Gherkin is three times taller than Niagara Falls and not usually open to the public, so this is a unique opportunity to get to the top of a London landmark and raise funds for the charity's work with vulnerable children. Participants are asked to raise £200 in sponsorship as an individual or £800 as a team and prizes are up for grabs for top fundraisers. Register to take part here.
