Jorge Plan + BarryP

One option:

Day 1 - Bike / Short Run
Day 2 - Med Run
Day 3 - Bike
Day 4 - Med Run
Day 5 - Bike / Short Run
Day 6 - Long Run
Day 7 - Short Run

You could combine day 7 with day 3 and have an off day, if you want.  All the running should be easy so you 'save' your legs for the bike workouts.  Mix it up however it works best for you.  Drop a run, if necessary.

I am doing precisely this as a base winter plan.  I started with BarryP's plan.  Got up to about 27-30 miles a week.  3:6:9 with Monday as my rest day now.  I then started Jorge's cycling plan on TrainerRoad 3 weeks ago, which is 3 1 hour interval sessions every other day.  I laid those on top of the running on Mon, Wed and Fri.  So, now my week looks like this:

Mon:  Trainer Intervals

Tue:  6 Mile run

Wed: Trainer Intervals + 3 Mile run

Thur: 6 Mile run

Fri:  Trainer Intervals + 3 Mile Run

Sat:  3 Mile Run

Sun:  9 Mile Run

Depending on time, I have done bike and 3 milers as bricks or have done one session in the morning and one in the evening.  I've just let my work/family schedule dictate how I split those.

So far, anyway, this has worked well because I am running all the runs at easy Zone 2 pace.  My plan is to turn Sat into a full rest day if I ever feel like I'm getting too much stress or fatigue from both the intervals and running, but haven't done that yet.  Last night's neighborhood Christmas party, however, is making me think today may be the first time to put that "rest" notion to the test given how my head feels...

I'm a firm, firm believer in BarryPs running plan (which I've been doing long before I ever heard about BarryP via my XCountry coach in high school).  Short, easy runs are the key and the day of rest is definitely the key.

I believe that replacing a rest day with a long bike or whatever is detrimental to the plan and training.

I'd combine the two - but make sure to leave the day of rest as a complete day off.

Ive been doing

M - Bike, short run

T - Long run

W - Bike, short run

T - medium run

F - Bike, short run

S - Long ride, medium run

S - off

Has been working fine and can fit swimming in on tuesday and thursday aswell (well not anymore because of a hand injury).

ETA: All runs have been slow/easy.  My focus is on getting faster on the bike, while just maintaining (or slowly rebuilding) run distance.

Not really.  In fact, Barry would probably be the first to tell you that running every day can be a very good thing.  If you are running easy (that's the key), then you should never NEED a day off.

I'm assuming it's not just strictly running.  Someone can run every day with easy runs without a problem.  But when you add in significant bike and swim workouts, the body needs to get a day off.

That said - I've always been encouraged to take a day off (even when it was strictly running).

If you add in 'appropriate' swim and bike, then the body most certainly does not need a day off every week.  Nothing necessarily wrong with running a program that does include a day off on most weeks.  But it is rarely ever the 'key' feature.  And an equivalent program, that is just as effective, can almost always be structured without a day off.  What's best for a specific person?  It depends, of course.

Agree. I've found I can go hard on my swim workouts on my recovery days and recover just fine. I can't do any hard kicking sets, but I can get in a really challenging high-pace swim.

I believe I'm doing "appropriate" biking, layered on to my long and medium runs, then the easy runs I swim. No recovery problems.
