We are not machines. Stuff written in a book might sound good, and might be a good idea in general to follow, but it doesn't always work out that way. I've know people who were ready to race but didn't because they didn't have enough miles in a certain zone or whatever.
If you are supposed to have 1,000 miles over so many weeks, and you only have 850 miles, nothing magic is going to happen at mile 1,000 that didn't already occur at mile 850. 1,000 miles is better, but 850 will work. Maybe 300 would work. At some point your mind and body will tell you to start doing more.
When I first started riding, I rode 50 miles a day, 5-7 days a week, for many months. I rode as fast as I could also, way over normal "base" intensity, like it was a 50 mile time trial. I would not necessarily recommend others go about it like this, but I was into it and it worked good for me.
Brother, I'm going to cut through the bull**** right now. If you can do Mount Tam this Saturday or Sunday and not blow your knees and back out, or have a heart attack, or be so sore you can't go to work on Monday, then CLIMB THIS WEEKEND!!! As long as you think your body can handle it, consider yourself
"cleared" for intensity.
Climb it again on Wednesday if your body feels like it. Ride easy the other days of the week. If you are pressed for time get a quality trainer and ride 20-30 minutes at any intensity. Even 20-30 minutes easy will pay off. Stick with something like this for a month or so, and you will see big results in fitness as long as your body can handle it.
As far as the pain of the climb goes, it won't really get any easier. You will only fly up faster. That in itself is reward enough to compensate for the suffering factor, especially if you are dropping other riders.
As far as CTS goes, that's up to you. As a coach, I can tell you the best coach you will ever have is yourself. Coaches help you chart a proper course, but you have to still have to sail the seas by yourself.
There are so many different ways to train, and many of them will give similar results. Finding a routine that fits your life is one of the harder aspects of coaching. Whatever you do, make sure your program fits your life and gets the results you require.
Happy climbing!!!
