Craig,
I didn't know you were coaching. Good for you. About that kid working to lower his 5K time. So many times I have seen the average or below average kids set a goal and they persist, work hard, attack it with tenacity and then finally hit it. Those performances often become the highlight of the year for everyone on the team. Encourage and work with him.

scroll down to the 1600 meter race. Acosta was disqualified because with 3/4 of a lap to go go, he knocked Joe of the track while Joe was leading the race. Joe got back on the track and finished 2nd. Joe had run the fastest qualifying heat the day before at 4:11.

Regarding apples and oranges. I agree. My interest in running has always been competitive; as a runner and coaching others. But nothing wrong with running for fun; even the elite have fun. And it is completely possible to make one's first race a big one. You did that. But for most people they need to set milestones along the way and achieve incremental personal wins as they progress. And no matter why someone runs, I always encourage that method. It is not necessarily the correct way, but more beginning runners will keep running with that method. Less likely to get discouraged or injured.
Mike,
That 20 mile race is close to a marathon. I would definitely set up a 6 day a week training schedule. For some ideas check out this article

Art provided some good information on the downhills, but I would try and stay upright, not lean. The short step is important, otherwise you will heel-strike which is killer on long downhills. You want a fore-strike. And as he said it is hard on the quads… not to mention the calves… it is even harder than he made it sound :(
If you remember from some of the minimalist running shoe threads, people said they were very sore at first because they started running with a front-strike. Well that will be compounded on downhills. Here is the trick on downhill training. Do a downhill training day, and then uphill the next day. You will be working opposing muscles and will almost give those sore muscles a day off when you run the opposite direction. And definitely train on the course if you can. Craig if you ever do the Boston marathon, I think it is net downhill so this would probably apply to that course.
George,
You might also want to look at the coolinrunning site mentioned above. I sure would encourage you to run some shorter races. Just getting used to the organization of a race and running with others will be helpful. As far as pacing, I have seen a lot of below average runners in the middle distances, they are fair at 10K and get better as the mileage goes up. Pretty rare to see someone who is good across the board unless you grew up in Kenya.
I sure am enjoying this thread. To the OP and Eugene, sorry we got off subject but you inspired a lot of people which is a good thing!!
