prime biking exercise for core and for strengthening neck and shoulder muscles- the plank. first with just elbows and toes on the floor, belly sucked in, navel touching back bone, glutes contracted and tight, shoulders down and back, neck long- Work on holding that position for a minute. When you can do that, do it with one leg lifted. When you can do that, do it up on a smallish exercise ball, hold, one legged and then rolling the ball clockwise and counter clockwise, forwards and back. Do proper full body pushups, on the mat, then with feet on the ball.
Whe you ride, focus on keeping your shoulders pushed down and back. When you get off of the bike do some angle stretches, neck and shoulder rolls.
Once you have a proper fit, its all about building strength and endurance.
Congratulations on you Madone. I am madly envious! Maybe someday.
