ActionAid supporter Adam Chataway is undertaking his biggest challenge yet - running 6 marathons in 6 continents for ActionAid. He'll be raising money for the Lera Town school in Ethiopia. Read his first guest blog for ActionAid below.
This time next week I will be in the air and setting off for my first destination - Buenos Aires.
At this stage there are a range of emotions - excitement, trepidation, a little panic, a light smattering of fear and lots of anticipation. I feel like my running training has gone well and I've stayed largely injury free, which is a massive bonus.
Last week saw me run 75 miles including 14 miles on Friday evening and 20 on Saturday morning and it didn't feel too bad ( I even spotted a rather smart Vespa submerged in the Regent's Canal that I'll be returning to with a salvage team in November if James Cameron doesn't beat me to it).
This sort of milage is very much unprecedented for a rotund plodder such as myself and this time two years ago the idea of a marathon would have caused a fair amount panic but, right now, I don't feel too overwhelmed by the thought of what is to come. But at the same time I have no idea, no benchmarks, no precedents as to how I will hold up.
Doing one marathon is one thing, doing two in a week is another and then undertaking three in a week with a 200 mile bike ride thrown in for good measure something a bit different again. But there lies the beauty and the appeal of the undertaking - the mix of excitement and trepidation that comes from asking questions of yourself that only you can answer.
Having said all that the one thing I am really scared of right now is bicycle seats. One hour on an exercise bike maketh not a prepared backside so I am in the market for some industrially padded cycling shorts. And I haven't even had time to worry about chaffing yet!
