Tamron 55-200

I would have thought longer was better but it I think it depends where you stand near the track.
seems obvious but are you pro, track side? crowd etc??
 
others will be familiar with the track. 300 is nicer if you can manage it and IS is great at that range. also if it's 300 you can full back a bit and not be on the edge of your lens

But i guess you have IS built into your SLR body don't you :p
 
if you can afford the G SSM get it, if you can afford the 70-400mm G SSM get that instead (it's not just longer but faster aperture wise).
