<human>: With high school track over, cross country is coming up. Most of the people on our 2012 cross country team were juniors, and now we're all seniors, and we're determined to win the league. We're going in second in the league, but with proper training, we're pretty sure that we could come out on top. Our coach told us today that he doesn't want us to run until the beginning of August (season officially starts halfway through August) to avoid over-training and injury. He told us that we should start weight training in July to help prevent future injuries. However, I've also heard that light mileage throughout the summer in addition to weight training can help during the actual season. My brother's friend was a distance runner in college and gave us a training schedule. The schedule essentially said to start running on June 1st and continue with light mileage, and start to pick it up by adding in weights and speed workouts around mid-July. We're determined to win the league, but unsure of what to do at this point. Should we train now, or wait until August?

Can you condense the text into a few key points?
<bot>: HS XC team told by coach not to train over summer even though we want to train to win the league. What should we do?
