I think you use Canon. me too !
24-105 mm ----> I will use this one for starting point for snapshot. And you can get close to the runner
55-250 mm ----> This lens 55-250mm f/4.0 - f/5.6 IS ?
This is not wide lens but tele lens. When it is on your ASP camera .
It will be 88-400mm. Make sure your shutter speed is high in 250mm (over 1/400 sec)
I suggest you set your ISO to over 1000 when take photo for individual.
