Jeez! 285 miles? That's one short ride on a summer afternoon! You just need a lot more seat time!
Here's my two cents: If you don't have one, get a medium size magnetic tank bag. Besides being so very handy to carry essentials and emergency items, they make a very good marker for positioning your upper torso by feel.
For me, when riding briskly through curves and turns about short straights, the bag is just touching under my diaphragm as I am seated a couple inches ahead of the rise (ridge at the back) in the saddle, separating rider from passenger sections and just off the tank in front. Knees are gripping tank sides and I am looking just over the windshield with a light to moderate pressure, only, on the bars. The tank bag is offering just a little support but not too much and I lose contact momentarily and frequently with the bag as I am working the bike through the road course.
When droning down the interstate to get to the promised land, I am seated nearly butt-up against the seat rise, pecs are down and in contact with the tank bag, elbows nearly touching knees at the sides of the tank and my head partially behind windshield in the pocket of serenity at limit plus velocities (often high on the plus side, heh,heh). Tank bag is now supplying some considerable support most of the time and touch on the bars is very light.
City traffic is the uncomfortable time, as others have noted, sitting up out of touch with the bag and "steering' the beast thru stop and go traffic with right angle turns, etc.
Hells bells, I sometimes almost fall asleep on those interstate cruise sections sitting in the "down" or pocket position!
For reference, I am 6'3" with a 34" inseam. Your exact position will be somewhat different depending on your size and the tank bag of choice, should you decide to give my descriptions a try.
Excuse me, please, if I am preaching to the choir. Otherwise, I hope this is of some help to you.
BTW: as a certified (NSCA) strength and conditioning specialist; may I suggest that if you need more abdominal strength, use lower reps and higher resistance in your "crunches" as opposed to lighter resistance (or only body weight) and higher reps as many people do. The former builds strength and the latter builds endurance properties of skeletal muscles. Also, be sure to work "honest" back extensions in the same session with the same resistance and rep scheme as the abs to achieve all-around balance in the torso developement and functionality. "Honest" back extensions involve the arching motion of the lower back under resistant loading; not stiff back hip extensions, as is often an error in trainees. And, especially, don't train the same muscles two days in a row; take a day or even two off between repeat sessions.
