I'm not Kenyan

but I run a lot and I've done a few half marathons and am training for one currently. You have a great pace going, we have similar stats. My goal is to run the half in 7:30 pace and get under 1:45. My time currently is 1:49. I can hold 8 min pace for quite a while, but beyond that is out of my comfort zone. I can hold just below 6 min pace for a few minutes also. When is the one you are training for? My first one was on a whim. I was on vacation, and there was one being held that weekend so I signed up on the spot. Till then I'd only been running 8 miles recreationally and never thought about racing. My first one I ran an easy 1:54 and though I'd not done even close to the distance, I chalk my success up to a lot of HIIT type
intervals on regular occassions. I like to train hard, even when I'm not racing.
I also train triathlons so I cross train for running quite a bit. I find the bike helps my running tremendously and its when I got seriously into biking (and spinning) that my running times started to drop effortlessly. I have not been as much into weights lately, but last year for my half I was, I felt they somewhat hindered my training. I do weights on average once a week, a full body workout, compound exercises. I do core work 3 times a week-which is another HUGE factor in how I've run as of late. It helps so much when you start getting tired. I follow about 90% to the Paleo Diet for Athletes...I do like my ice cream though

Pre, during and post workout nutrition is a big deal when training for something like this. When I made changes surrounding my workouts I also found my energy and performance to skyrocket, not to mention a lesser recovery time after hard stuff.
I trained a lot for an October race last year and didn't watch my nutrition or stretching much. I got shin splints in the worst way and had to spend 6 months getting rehabilitated from them with a lot of professional intervention. I have since gotten orthotics and know what to do if they start to come back, but it hasn't been an issue yet (knock on wood). I take a glucosamine/chondroitin supp. which has been the magic bullet for me. Its when I started that, that I started to get better more quickly. My joints feel so much more flexible and smooth. Do NOT neglect stretching. I'm a big fan of stretching.
Get friendly with a good sports drink/gel. I use Accelerade and I swear I should get some sort of kick back for the amount of free advertising I do for them! Accelerade has a ratio of 4:1 carb/protein and has made a lot of difference. The company also makes gel that I take on long stuff with me. That or "gu". Try different things, not everyone is the same when it comes to that stuff. Just be sure you do what you will do in the race, when you train. No surprises on race day.
The only other advice I can give is to increase SLOWLY. The 10% a week rule is golden. Do HIIT 1-2 times a week and DON'T overtrain. Runnersworld.com has an awesome custom workout thats free. Based on your stats and goals it will pop up a training plan for as many weeks as you need until your race and in a safe way. What I've learned since my first half is that besides your long run once a week, its really not about quantity, its about quality. Tempo runs, HIIT and easy runs are all equally important but do not run every day. Cross train or take the day off between running days.
Do you have a heart rate monitor?
Ok I've rambled long enough. If you have any other specific questions you can PM me.
Good luck!
