I have tried resting and running a bit the day before.
I feel better with an easy run of half an hour the day before.
You have to try different approaches before finding out what works best for you.
Rest or run this time, do the other way round in the next... This way you'll find out what your body requires.
Same thing with pre-race meals.
I might try just doing an easy run the day before if I feel up to it and as for pre race meal, I had not even thought about that. I am an erratic eater but do not want to overload too much, is ceral a good think for brekkie followed by maybe a jacket potatoe for lunch or some pasta?
I know we are going for a p*ss up after the race so I shall probably be on the beer but as for 8 pints....I think I probably wouldn't able to run in a straight line or more likely I would be out cold.
For a 5k you don't need to worry about diet too much just eat a normal healthy food that you enjoy - what you suggest sounds absolutely fine. If I get up really early for a run I often don't have time for breakfast so I often eat my breafast when I go to bed then have a milkshake when I come through the door if its been a long run.
