One scene is a school track race.
I remember the book being well written.
Probably released in 90s or 00s.

Could it be The Warrior Heir?

Or the sequelThe Wizard Heir

I think this one is actually closer to the plotline you described...if I remember right from when I read it.

I don't think so, from the sounds of it it. Grrr, this is bugging me!

so I still don't know what this blasted book is!!!

SOLVED (I think so anyways)!

Blaze of Glory - The Laws of Magic #1 by Michael Pryor

Aubrey Fitzwilliam is the son of a prominent ex-prime minister. He's also brilliant at magic, but he's stuck at military school. At least he has his best friend, George, there to back him up. George would follow Aubrey anywhere - and with Aubrey's talent for thinking up impulsive and daring schemes that will get them both in trouble, that's no easy thing to do.

At a weekend shooting party at Prince Albert's country estate, the boys find themselves in a hotbed of intrigue and politics. They discover a golem, a magical creature built to perform one task: to kill Prince Albert. Aubrey and George are hailed as heroes for foiling the attempt on the prince's life - but who sent the golem, and why? Aubrey is far too curious to let the authorities handle this one, and he and George start investigating.
