I did write to them but they never replied. I'm guessing my little email got lost in the big machine that is McMillan Running. It must probably be a very lucrative business for Coach Greg.
Bummer. Well I guess I'd keep two things at the forefront when mixing running+strength.
1) Keep easy days easy. So with the strength program above, you've got leg strength exercises which changes an easy day to a moderate/hard one.
2) Avoid putting similar strength workouts on back to back days.
So if we go back to their original plan:
M- OFF
(Easy)
T- Easy + Strength
(Moderate)
W- Easy
(Easy)
R- Hard + Strength + Yoga
(Hard)
F- Recover/Cross
(Easy)
Sa- Easy + Drills
(Easy)
Su- Long
(Hard)
This plan has
four easy/off, one moderate, and two hard.
M- OFF
(Easy)
T- Easy + Strength
(Moderate)
W- Easy+ Strength
(Moderate)
R- Hard + Yoga
(Hard)
F- Recover/Cross
(Easy)
Sa- Easy + Drills
(Easy)
Su- Long
(Hard)
This plan has three easy/off, two moderate, and two hard.
M- OFF
(Easy)
T- Easy
(Easy)
W- Hard + Strength (loss of group run)
(Hard)
R- Easy + Yoga
(Easy)
F- Recover/Cross
(Easy)
Sa- Easy + Drills
(Easy)
Su- Long + Strength
(Hard)
This plan has five easy/off, no moderate, and two hard.
M- OFF
(Easy)
T- Easy + Strength
(Moderate)
W- Easy
(Easy)
R- Hard + Yoga
(Hard)
F- Recover/Cross
(Easy)
Sa- Easy + Drills
(Easy)
Su- Long + Strength
(Hard)
This plan has four easy/off, one moderate, and two hard.
M- OFF
(Easy)
T- Easy + Strength
(Moderate)
W- Easy
(Easy)
R- Hard + Yoga
(Hard)
F- Recover/Cross + Strength
(Moderate)
Sa- Easy + Drills
(Easy)
Su- Long
(Hard)
This plan has three easy/off, two moderate, and two hard.
So I guess my order of preference would be:
1) Try to do hard run + strength + yoga on the same day
2) Drop/move the yoga off Thursday
3) Drop the strength workout on Thursdays and do one strength per week.
4) Do this one:
M- OFF
(Easy)
T- Easy + Strength
(Moderate)
W- Easy
(Easy)
R- Hard + Yoga
(Hard)
F- Recover/Cross + Strength
(Moderate)
Sa- Easy + Drills
(Easy)
Su- Long
(Hard)
But go really light on the Friday leg moves. If you find the leg moves to be too much on Fridays, then drop that strength workout altogether.
