In reply to stuartpicken:
I had similar training aims, as my main ambitions were trips to the alps. I did too much (combination of climbing, running, wieghts, etc.) and became sick with Chronic Fatigue Syndrome. Slowly recovering now (3 years later), but would definately advise erring on the side of caution.
I got up to long runs of 15 miles, at a slow pace, but used a HR monitor rather than nose breathing to keep the pace down. I was doing the long distance running because it was difficult for me to get to the mountains as often as I would like. So it was an alternative rather than an addition to long mountain days.
I would suggest focusing on your 'key' training sessions, those that are most beneficial to your long term objectives. These would be your long mountain days, and the crag and indoor climbing sessions. If you are getting say two of each of those in each week, do you really need long runs as well? Your getting your aerobic training from your long mountain days.
Supplement these key sessions with weights, and running, but if you have had a hard mountain day, make the next day an easy short run. A recovery run.
So focus on the key sessions, but go by feel for the other days. If you are really tired or sore don't worry about missing a day while you recover. In the long run you will be better for it. As someone else has already said, rest and recovery is important too. We get fitter in the recovery periods between training sessions, not when we actually doing the training!
I suggest the key would be that old phrase of 'listen to your body' (says someone who failed spectacularly to do it himself in the past) rather than a mechnical, formulaic approach. Particularly if conditions, partners, etc. make it difficult to aim to follow a plan for each week.
Sorry if that is not what you wanted. I am very interested in what comes out on this thread.
Hope that helps
