Ditto. Felt good at first, so I went straight back into training quite hard, but about 2-3 weeks after a big race it hit me. Was shattered for a week. Could have been illness or something, but I wonder if I simply didn't rest enough immediately after the race.
I'd take it easy for a couple of weeks (no I wouldn't, but I should!), I suppose a sort of reverse taper if you like, then couple of weeks normal training then couple of weeks taper again.
