Jacobsburg for the beginner

OK, so my intermediate level husband is taking me to Jacobsburg on Friday. I'm an absolute beginner, this will be my first "real" trail. Since he tends to overestimate my abilities, I'm hoping you can give me some tips.

Which is the best trail at Jacobsburg for the absolute beginner? I'm 37 years old, and just got on a bike a couple of weeks ago. I ride 2-4 miles every day around my neighborhood paved roads, and some large gravel/dirt roads.

Thanks for any advice!
