Stratford-upon-Avon Marathon

[El Gordo]

In the UK, there's also the Lochaber marathon the week after London. This is in Scotland, and said to be very picturesque. Very different from London, but many people enjoy it.

Take a look at http://www.marathonguide.com to see what else is going on around that time. (You may want to look at the 2003 events at the corresponding time, as not all the 2004 races are up yet. They tend to stick to the same weekend the following year, but obviously do check with the relevant websites).

Let us know what you decide. I'm planning on doing one the week after London too. Currently it's a choice between Stratford, Lochaber, Padua (Italy), Madrid and Wroclaw (Poland). I'm not in any hurry to reach a decision, but will probably go for one of the non-UK ones, even though both are well thought of.
