Yes. You could mix just these five workouts, plus easy runs, long runs, and strides, and get over 95% of the way to your peak potential for everything from the mile to hilly cross country to a road half marathon.
1) 30-40 minutes at 5k effort + 40-45s/mile
2) 4-6 x mile at 5k effort +25-30s/mile w/ 60s recovery
3) 5-8 x 1k at 5k effort w/ 2:30 recovery
4) 8-10 x 400 at mile effort w/ 60s recovery
5) 6-8 x 2-3 minutes on a steady uphill hard but controlled (similar to 10k effort) with easy jogdown recovery
Hell, after writing that out, you could probably do it with any four of them (although leaving out #4 would affect your mile, and leaving out #1 would affect your half marathon), and get pretty close to that with just the "odds." Coaches have a place in keeping you accountable and protecting you from your own worst instincts, but the workouts aren't magic.
