WHAT'S THE WORKOUT? 20 minutes at aerobic threshold pace (slightly slower than marathon pace), then 6 x 40 second hill repeats at 3k effort, and finally 4 x 200 at about 34 seconds. WHY ARE YOU DOING THIS? This is a classic tune-up workout. With a race in a week, I don't need to get in any more fitness work, but it's a good idea to reinforce some of the positive steps I've made through my training. I'm a very aerobic runner (meaning I respond best to long-distance effort-based work. The 20-minute AT (run near my marathon pace), is enough to stimulate my aerobic fitness without taxing my body too much (in a typical base-building session, the AT would be 60 minutes). The hills and the 200s are very similar in purpose to one another. While the AT targets aerobic endurance, the latter two parts of the workout target the opposite end of the fitness spectrum -- neuromuscular coordination. They reinforce efficient running form (especially the hills) while improving run...
