Lamentably mine are in a box and rarely see the light of day. I've contemplated hanging them up on a nail somewhere - the garage perhaps - but I have not got around to it. I do like medals and should make more use of them as they are the best 'reward' for finishing imho.
T shirts usually find their way into the bin after 12 months or so after being used to sleep in. I only have one longsleeved one left, which has my name on the back. I had two mugs over the years but the wife has a special talent for breaking crockery. I'm planning on doing a race next month and there is a finishers mug - I resolve to keep it on a special shelf in my man cave.
I once received a pie - that was 'interesting' & also a running hat - Turkey Trot at 'Keyworth' I think.
Yesterday I ran the Christchurch Marathon and finishers received nothing - very, very disappointing.
