As Wilkie said it's not a very exciting city but when you do a marathon it does hinder any sightseeing on foot before and after.
I thought the marathon was great. The crowds that turned out and the people volunteering really made this so good. The course was fine. Nice and flat, mostly. Running through a garage showroom? Hehehehe, well more the forecourt. Yes that was strange.
I did a PB of 3:50 and that was 7 mins quicker than the Robin Hood two weeks before so I'm very glad I went. Lots of "Allez, Ed!" was really appreciated.
As ES said, the weather was perfect. Hardly a cloud in the sky, which normally I wouldn't want in a marathon but it wasn't really hot at all and the organisers had the good sense to start the race at 08.30, when it was quite cold but ideal for later on.
If you can get a cheap flight, I'd recommend the marathon and maybe travel by the excellent trains to Lausanne (Olympic Museum is good) or other cities to do some sightseeing. 1-2 days in Geneva was enough for me.
