I'm not very interested in medals, and the bigger and chunkier they are the less I like them. I think the VLM one is even nastier than the FLM one was. Looks like something Jimmy Saville would have worn.
Most seem to be very cheap and poor quality, don't even have the event name on the medal sometimes, and even if they have the name, they often don't have the date (means they can use any left-overs the following year). British race organisers seem to think that as long as they get a medal out, it doesn't matter if it's crap.
Of the ones I've had that I liked, most have been from overseas events, rather than British. The Amsterdam Half Marathon was quite nice, and the Transbaie race in northern France does a good medal.
The Somme Poppy marathon medal is good - enamelled, with a poppy on it (surprise!).`
The nicest English race medal I've got is from the Burham Beeches half a few years ago.
