What is the workout? This workout is super simple yet super effective: after a 10-15 minute warmup (starting real easy and gradually increasing the effort) you run for an hour at aerobic threshold effort. When possible, do it on a course with rolling hills. Finish it off with an easy cooldown of 5 minutes to a mile. So what's aerobic threshold? In my running lexicon, it's a moderate-intensity, high-end aerobic effort; in terms of pace, it ends up being slightly slower than marathon pace but slightly faster than normal run pace. For me, depending on the day, my pace will average somewhere between 5:30 and 5:50 per mile. That said, notice that I described the workout as "an hour at aerobic threshold effort ." Like with other WOTW installments, I feel that effort is way more important than pace. Some days you'll feel good and naturally go faster, some days you'll feel rough and have to grind it out a little more. Some courses will be a little flatter and faster...
