We paid by bank transfer a few months ago which was pretty straightforward.
I am on the fourth week of a training plan from Runners World which I have used three times before and so far I have always exceeded the target times but they are hard work!
Not sure if I have done a marathon as undulating as this one though so I am expecting the worst. I am doing Snowdon marathon on October 17th which was booked before Athens so I a now using this as a long training run!!!
