In reply to mattck:
I carry a lot more than I used to, especially in winter. Chris Smith's death last October has even further highlighted the importance of personal hill safety to me. Survival bag, hat, gloves and 'winter' waterproofs (still running ones though) and phone as standard. Food if I'm heading for longer (practicing eating for long events)
As girlymonkey says, better to carry too much than too little
I'm well experienced of racing in crap conditions in the high fells, and all this may seem excessive for 90 minute easy run on the North York Moors, but it'd be hella embarrassing if a silly slip on an easy run nearly did for me - I couldn't live with the shame!
Now the weather is more predictable I'm more likely to just head out in shorts and T-shirt, but if out for longer will carry gear, and in the high fells a waterproof and survival bag and phone are a minimum.
Carrying heavier gear in training makes mandatory race kit feel like nothing. Though again I'll go by the prevailing conditions - lightweight waterproof is next to useless if it's raining sideways
