i know this is a troll but....
The whole point of aerobic BASE is to build an AEROBIC BASE, off of mostly easy runs to help develop your aerobic systems in preparation for cross country. Along with this, maybe 2-3 weeks into your training, depending on how you feel, you can add in some tempo and fartlek workouts to help increase your lactate threshold, but at most you would do these 2 times a week, maybe 3 if you made your long run a harder effort. The workouts you are describing A) do not stimulate your aerobic base system and B) are workouts designed to increase your VO2 max, which is supposed to be done later in the season. By repeatedly doing multiple hard workouts, and not to mention racing, you are essentially beating up your body without allowing it to rest and build up a base, which is the entire point of summer training. Weights are fine as long as you don't overdo them and get injured.
