I won an online contest from runnersworld.com that gave me a free entry to the Country Music Marathon or 1/2 Marathon! I entered thinking what most everyone think, "I never win anything." Well, my first actual race is a 10k next weekend, then maybe a 5k the next. Then I will have 3 weeks to ramp up to a half-marathon. How am I going to do that?????? Any advice would be greatly appreciated! I am going to do the 1/2; I just want to do it well.
