Hi. I'm trying to figure out which training program to use (5k, 10k, etc) and could use a little help. I ran cross country for my high school this year. Next year, I will be attending Purdue University and would like to compete in cross country. They run a 8k I believe in their races. Also, I will be participating in ROTC and would like to get my 3 mile time to 18 minutes. I was wondering which training program I should be using in order to be competitive in both of these? Should I be training for a 5k? 10k? Some totally oddball training program? Any help is welcomed. Thanks.
