Are you doing BarryP? I have a similar workout schedule (though occasionally 4 rides a week). I plan my recovery run days with my bike days (so short easy runs). I tend to separate them but sometimes it's only by 1 hour or so.

Yeah, trying it out this winter. Combining it with the Sufferfest build plan, but skipping the recovery rides.

I was able to run off of the bike this morning and felt fine. Again these are slow / easy runs, not going out to kill it. I was hoping someone would chime in with detailed knowledge on recovery. If I wait until lunch to run, is there a recovery process underway that is then interrupted? Or will your body simply recover anytime you're not exerting yourself?

Probably overthinking it, but just curious from a physiological standpoint.

I'm a big fan of getting a decent break between sessions; my wife less so when it eats a weekend day up. This Sunday I had 5hrs on the bike, a 10 min run off it, chilled for about 4 hours, then had a 2200m LCM swim to do. Getting out for the swim was hard but afterwards I was ok. I couldn't have done it and felt OK if I'd stacked it right onto the bike/run.

I'm currently looking at running 6x weekly and cycling 3x. That means three days I'll double up (hour on the trainer + 30 to 45 minutes on the treadmill).

My options are to do the ride in the morning and the run at lunch, or just get up earlier and knock them both out in the morning. From a recovery perspective it seems like getting them both done in the morning and then having ~22 hours to recover would be optimal over the split approach. My rides tend to be fairly intense (Sufferfest) and runs are more of a low HR focus.

Last season I did the BarryP plan but 5 runs per week and combined it with the TrainerRoad General Build plan. My basic schedule looked like:

Mon: Lunch - Run 50 min
Tue: Morn - Bike 60 min (intervals)/25 min easy treadmill
Wed: Morn - Bike 30 min (recovery); Lunch - Swim 2000m; Evening - Run 10km track session with tri club
Thu: Morn - Bike 60 min (intervals)/25 min easy treadmill; Lunch - Swim 2000m
Fri: Morn - Bike 30 min (recovery); Lunch - Run 75min; Evening - Swim 2500m
Sat: Morn - 90min Trainer (intervals)
Sun: Morn - Outdoors 3hrs aerobic ride (z2)

I found that my legs were very fatigued but I could complete the scheduled workouts. I'm lucky in that I can schedule in run/swim training during my lunch break at work. I found that progress was ok on bike/run, but this year I'm planning on doing 12 week focus blocks and just maintaining the other. So e.g. ramping up run volume to 80-90km per week and cutting the bike back to 2 sessions a week.

I stacked mine a lot last year when I was time strapped until 6:30pm. I'd sit down and eat a snack/hydrate for 30 minutes between the two. It was never that bad as long as they weren't back to back hard workouts. I don't think it's optimal but I would guess it's better than training less
