Narrative:

On descent we had been given maintain 290 KTS for traffic and several vectors with a crossing restriction. I did one heck of a job of maintaining 290 KTS; but failed to slow to 250 below 10;000 ft. I detected the error and immediately reduced power; approximately 30 seconds after reducing power ATC asked us our speed. Hate to sound as if I am making excuses but here it is; long duty day (on duty approx 12.75 hours); gate return 1st flight of the day due to ATC; flew 3 legs without FMS and APU; crossed front 3 times (turbulent conditions); complex environment and inattention to detail. Pay more attention; do a better job of briefing pilot not flying of my intentions. Don't be afraid to call-in fatigued.

Title: A fatigued CRJ700 Captain failed to slow to 250 KTS below 10;000 FT after ATC asked him to maintain 290 KTS while being vectored and given a descent with a crossing restriction. A long duty day in weather was a factor.
