First off, make sure your mileage is high enough. Daily runs of 6+ miles/day Monday-Friday should occur. Once you're constant with that, add in intervals, repeat 400s/800s/miles such that you have a total training volume that's high enough. Fartlek(sp?!) runs are also pretty interesting. Weekends are optional, but highly recommended. Long slow distances to recover.
I ran cross country/track throughout high school, but didn't care much for the longer distances so my best training run was only 9miles in ~56 minutes.
You posting a current training schedule/log would probably be the best way for us to help you.

Imo you dont need to go longer than 12 or 13 for you longest training runs. Save the 15+ milers for marathon prep if you decide to do one.
If you want to do repeat intervals for speedwork, i think longer intervals like 1200s or miles are more beneficial for a half marathon than something like 400s.
You are already able to run 7+ miles at close to or better than goal pace in training, so just inceasing your endurance by building up to longer runs will probably get you to a 1:50 half.
I respectfully disagree as to taking weekends off. You want to build in at least one long run per week and weekends are the best time to do that. Also, with a good schedule, building a base of 30+ miles per week is not necessary. However, intervals and fartleks are quite useful.
I generally agree with capping the long runs at 12-13 miles. In fact, one could do as few as 10 on the longer long run days. However, inasmuch as the OP indicated he wanted to increase endurance, one or two at 15-16 miles would not be a bad thing. NOTE: as a general rule, one would want to alternate the long runs, so one could do the following in a 16 week schedule (this is just the long runs:
week 1 - 6 miles
week 2 - 8 miles
week 3 - 6 miles
week 4 - 8 miles (3/1)
week 5 - 10 miles
week 6 - 8 miles (3/1)
week 7 - 12 miles
week 8 - 10 miles (3/1
week 9 - 14 miles
week 10 - 10 miles
week 11 - 16 miles
week 12 - 13 miles
week 13 - 10 miles (3/1)
week 14 - 8 miles
week 15 - 4 miles
week 16 - race
On the 3/1 days, you run the 1st 3/4 of the run at a comfortable long-run pace (think being able to talk in sentences) and for the last quarter you run within 30 seconds of race pace.
For the OP to do a 1:50, he will need to run approximately 8:23 per mile over the course. For the long-runs, comfortable can be about 10:00 to 10:30 per mile. On 3/1's, the last quarter of the run would be about 8:45-9:00 per mile. The notion on the 3/1s is to kick it at the end, which will build the endurance for finishing the OP seems to feel he needs.
