Vertical rush

One man went past me wearing what looked like ski boots and I heard a rumour that the fastest finisher had got to the top in 3 mins 53 secs. If so, that's not far short of four steps or 30-odd inches a second.

Still I was pleased to get to the top of Tower 42, the former NatWest Building in the City, for Shelter's Vertical Rush event before breakfast this morning in 8 mins 52 secs. That meant I missed my friend Fiona's offer to double my sponsorship if I did it inside eight minutes, but she cheated by having me shift heavy boxes of magazines around north London to tire me out yesterday.

I've never been that high in London before, except in a plane, and the view from the 42nd-floor champagne bar (minus the champagne, alas) is certainly worth seeing. It's no longer the highest point in the City of London, however, as I discovered looking out of its windows. The adjacent Heron Tower (pictured), still under construction, has a few steel girders going higher still, and when it's finished it will be 100 or so feet taller than Tower 42.

You can sponsor me for doing Vertical Rush and the London Marathon in aid of Shelter here.
