onlysevenmoremiles - I was 25 yesterday. 6th mara next month then 7th in October. VLM next year will be 8th! Will be pleased getting 10 maras under my belt by the time I'm 30 
No Garmin for me - not keen on them. I've got a Nike+ Sportband and it is so precise, I wouldn't want anything else.
May check out that new Nike GPS watch but not overly fussed seeing as I have no problems with the Sportband and it's a fraction of the price.
Tempted to go watch VLM now though since my local club would let me in on their bus (I'm not a member but know a lot of the team well) but got a 16/18m planned so should really get my own Mara schedule up to speed!
