I run at this distance and shorter and have a couple of general comments/tips for mid-size to smallish races. Big races are a different story:
1)
Depending on the field size and security at the race, you may be able to get right in there at the edge or just in the crowd pre-race, up to a few minutes before the gun. UWA or WA is perfect. Just get out of there when you hear the starter's command... 2) Pre-race, you will get your serious "game faces" in the first few rows. Don't encroach too much up there or you might be wearing your lens hood for a hat. Your joyful comaraderie improves working your way back in the crowd. Your hammed-up antics, costumed runners, and "personal goal" first timers want to be documented. Just depends what you are looking for.
3) The first half of the race provides you with your "prettiest" runner shots. The last 25% of the distance in the race provides you with the same beautiful form and stride from the leaders, but diminishing from there back into the field to grit and determination; to distress; to pain; to suffering, to body function failure, etc. Shoot what you want to say about the race.
4) The finish line provides you with the same emotional ops, but everybody wants to look good for you if they know you are there. If you can stake out a spot to capture the clock and expressions, you are golden. Hard to do that though, unless the race is large enough to have multiple clocks in the finsihing area.
5) Don't forget candid shots at the awards ceremony.
Hi Pete, thanks for taking the time to comment and leave tips etc. 
Shots 2 and 3 are WA at the start of the race. Once they'd lined up for the race, there was definitely no getting in there as they were crammed together like sardines!! 
There was only one person that i saw in fancy dress, to be honest. Everyone else was taking it quite seriously.
I only shot the start and finish of the race, as they close too many of the roads, and i was worried about not being able to get back for the leaders finishing. It was a bit of a last minute decision to shoot this race, so no planning was done unfortunately. I'll know better for next time hehe!
As for them wanting to look good for me at the finish line. Trust me, they had no interest in me whatsoever. The guy coughing up blood, practically vomitted on my feet.
Well, okay he wasn't quite that close, but that shot's not cropped, and it was with a 50mm. I was on the left of the finish line, inside the fence, and the pro tog was on the right.
I didn't stick around for the awards ceremony, if there was one; i didn't even see the end of the race. Once my 6gb of memory cards were filled up, i left. I'll either have to get more memory for next time, or be far more selective...
I'll definitely be shooting more sporting events, and hopefully i'll get to a level where i can start earning money from the shots, for that next photographic purchase.. Lots to learn in the meantime though, so thanks again for the tips.
