This is always a good day of the week to rest, particularly if you ran long over the weekend. All of the Mondays in the schedule below are designed as days of rest, but if you want to do some extra stretching and strengthening today, be my guest. Tuesday: Modifying a term that I use in my other marathon training programs, let’s call this our Sorta-Short Day. You’re still recovering from your weekend long run, so don’t go too far. I suggest that in Weeks 8, 6, 4 and 2, you run 4 miles at your marathon pace–or faster. In other words, run short but at a good speed, and I’m not going to define what is a good speed. You being an experienced runner should know how fast you want to run, or if you want to run fast at all. In Weeks 7, 5, 3 and 1, run 6 miles but at a comfortable pace, one during which you can converse easily with a training partner if you desire. Or not converse if you’re a Boring Individual. Wednesday: Today’s workout is Stretch & Strengthen, because that again is a term I’ve used frequently in other training programs to designate semi-rest days on which you do some alternate training, but not too much. In honesty, I don’t care what you do today as long as it is not running. If you want to run more than three days a week, you should have chosen another program. Cross-training is an option today too: cycling, swimming, even walking. Or some combination of that with work in the gym. Thursday: This is your Sorta-Long Day, balancing the Sorta-Short Day on Tuesdays. The mileage varies from 6 to 8 miles most weeks with a single 10-miler thrown into the middle of the program just to prove you can do it. Running these Sorta-Long Runs at an easy, conversational pace makes the most sense to me. However, if you feel you need some extra fast running, consider converting the 6-miler in Weeks 7, 5 and 3 into a “3/1 run,” a term I use in many of my intermediate and advanced training programs. Run the first three-fourths of the run (4.5 miles) at a comfortable pace, then finish the final fourth of the distance (1.5 miles) at an up tempo. You don’t need to sprint in; just run somewhat faster. Friday: Another Stretch & Strengthen day. Do something similar to the workout prescribed for Wednesdays. This might mean that if you cycled or swam on Wednesday, you might want to walk today or simply spend your time in the gym hopping from machine to machine. I’m not going to tell you everything to do. You’re a Big Boy–or Big Girl. Saturday: This is your second Rest day. With a long run planned for each weekend, you want to make sure you have plenty of time to rest both before and after. In this schedule, I’ve prescribed doing your long runs on Sunday, because that’s a popular day for experienced runners. If you would rather run long today, that’s okay. In fact, feel free to juggle all the workouts to suit your particular lifestyle. And you don’t need to always run the same three days all eight weeks of the program. Just maintain the regular pattern, and you’ll be okay. Sunday: Run long. Today you do your Long Run, and you’ll notice that the build-up in this Senior program goes from 12 to 20 miles, not the 6 to 20 miles in my 18-week Novice programs. That’s because you’re an experienced runner. You train regularly 52 weeks of the year and never get out of shape, so doing a 12-miler is no big deal. I’ve prescribed that distance for Weeks 8, 6, 4 and 2 with longer runs Weeks 7, 5 and 3 leading up to the marathon in Week 1. Only one 20-miler? Do you really want to run more than one? Do so in the odd-numbered weeks. Important: Do all of your long runs slower than your marathon pace. Don’t overtrain!
