Running!

Okay, so I've decided to take up running and I'll be running the Scotiabank 10k run in May. I'm a new runner and I'm hoping that you guys can give me advice. I'm also curious to know about running form, I've heard of both toe-to-hell and then midfoot striking, which one is better?  But any information that you know about running, I would love to hear.

Cheers!
