The Stones are currently in Walnut Creek, CA. Late flight last night, but it was nice to wake up and be here. Overcast, foggy, looks like tomorrow is gonna be the “bad” weather day, with more pronounced winds 20mph+ and periods of heavier rain. I’m not sure what some people in other threads are whining about, Sunday morning is a race day forecast I would take in a heartbeat. 53-54F, overcast, light steady rain, 7-10mph winds. Yeah, as a bigger guy, I would like a bit cooler temps, but the cloud cover, wind, and rain offset a few degrees. The sun is usually my biggest nemesis, so I’m loving these forecasted conditions.
To touch on a few topics. Singles versus doubles. There are many successful examples of runners I know and coach who do one (singles all the time) or the other (doubles all the time, with maybe a single on long run day) or a hybrid version (ala AJ, 3-4 days of singles and 3-4 days of doubles). To me the most important parts of the formula are stress and recovery and intensity.
Like Smoove, I have fallen into favor with singles at my age. I like doing 4 to 5 double digit runs a week, and having the 24 hours of recovery in between. Being able to regularly treat a 10+ mile run as “easy” or “recovery” is good medicine for the marathoner in training.
In my younger days, and for many athletes I coach who might have time constraints, dividing 10 miles as 6 / 4 or 12 miles as 7 / 5 made more sense. There is the bonus of triggering metabolic mechanisms by running more frequently, by training your body to develop a more constant cumulative fatigue, but there is also the extra laundry, extra showering, and less continuous time on your feet than singles.
Which, I think, is why you’ll see quite a few regular successful posters on our thread (slo, AJ, Sub 6:00 immediately come to mind) settle into more of a hybrid approach as they kind of get the best of both worlds.
I think no matter which of the three options a runner personally decides works best for him or her, that the intensity (and recovery) within that schedule will play as much of a part of success as the schedule itself.
sans - To answer your question a bit more specifically...
I like what you have decided on based on what’s realistic for you with work/family/etc. I would guide you to 4-5 days of 30-45 minute doubles with two devoted quality longer days. In fact, I love your 5 x 2 mile workout at this point in your training cycle. I think for most runners, 10-12 miles of total MP volume is a comfortable maxing out point in training. What I would expect you to do as you approach race day is to extend the periods of duration that you are running MP, so a series might look like:
5 x 2 miles
3 x 3 miles
7 miles
4 x 2.5 miles
8 miles
2 x 5 miles
9 miles
2 x 6 miles
10 miles
Etc. You could keep that as one of your weekly workouts and rotate it as part of your midweek workout or embed it in your long run.
Like AJ and darkwave alluded to you, you will also want to incorporate some HMP or T running in your workout rotation. Maybe start with a cruise interval type session (6 x 1 mile) and build from there:
3 miles
4 x 1.5 miles
4 miles
3 x 2 miles
5 miles
2 x 3 miles
3 miles / 1 mile / 3 miles
Again the iterations are innumerable.
And to kind of tie everything together about singles v doubles, stress v recovery, younger runners v masters, two workouts v three workouts...
I present to you the training of Ray Bentley. He was a successful masters runner who in his forties and fifties ran numerous marathons in the 2:40-2:45 range off of a simple, repeatable weekly schedule. He came to this schedule after suffering a few stress fractures earlier in his career from not giving the proper balance to the stress v recovery.
M - 10 miles at 8:30
T - 10 miles at 8:30
W - 13 miles total. 8-13 miles at MP based on how he was feeling and how close he was to race day.
Th - 10 miles at 8:30
F - 10 miles at 8:30
Sa - 20 miles at 7:00-7:15
Su - Rest or 10 miles at 8:30.
73-83 miles a week. Not high in intensity, but he said the slow singles built his strength. Running an honest long run and a weekly pace workout dialed him in.
Not saying this is the best way to train, or that the way I train or anyone else trains is the best way to train, but that when you find the right stress and recovery, you find the right balance, and you are consistent over time, you can make your schedule work for your goals.
