Forum regulars will know I like to do a bit for charity but I'm limiting myself to a single event this year because I'm aware of 'Giving Fatigue'. My other challenges (Silverstone Half Marathon, Bupa10k etc) will be just for my entertainment.

That one event is for Shelter, the housing charity. Having missed out on a 1Km Guinness World Record for 'Tower Running' by just 70 metres last year, on March the 5th I'll be trying again during their Vertical Rush event at Tower 42. Now in its fifth year, this race is held up the 902 steps and 51 floors (nine unnumbered) of the former NatWest Tower in London. Last year I climbed the 165m/542ft office block nine times in non-stop succession to raise funds - thank you for your support in 2012 (www.justgiving.com/verticalmile) and 2011 (www.justgiving.com/verticalrushing). However, because the tower was slightly shorter than the 920 step/180m I'd been told, I failed to get the 1Km/hour vertical record by about five minutes and didn't hit the hoped-for vertical mile either, stopping at 93%. As I said when I found out much later, "******."

So I'm back in 2013 to try again, planning to cover the 102 flights of steps TEN times as quickly as possible, to secure that vertical mile once and for all. I was very disappointed to discover I'd not got the record last April, when I was able to get an accurate figure for the height of the top floor above street level. Happily, Shelter have agreed to let me try again and I've been training hard to get my heart, lungs and legs in top condition to join a very different Mile High club! It's quite a strain physically but I enjoyed myself last time and I'm keen to give it another go. Raising money for a very important cause is just a bonus, but I hope people will want to support what I'm trying to achieve. My burning thighs will thank them!

So my 2013 target is 510 floors, 1020 flights of stairs and 9020 steps in total and if I can cover the first vertical kilometre (3281ft) in less than an hour I'll get the record too. You can see my video of last year's attempt at http://youtu.be/sMzV8INPEqM and to give this thread a hint of Geocaching: http://coord.info/GC44XD6

Any help to hit my £180 (I've already given £40 to take part) target would be really lovely of you. You can support my efforts via www.justgiving.com/mileup. Thanks! :socool:
