Coaching is a big business, and some folks like to make things as complicated as possible to imply they have found the holy grail of training but like smaryka says, mainly the key is just to ride your bike a lot in the next 9 weeks.
If it were me with 10 weeks to prep for a race I would probably do something similar to the below. If it were a TT, I'd do it pretty similar except make some adjustments in the final 4-5 weeks (I'm assuming it's a race because only a sadist schedules a 60mi TT and at least here in the US 60 miles is a very common distance for Cat3-5 RR).
I'm assuming I'm coming into the schedule with some basic aerobic fitness and the plan is to work up to a 3-3.5 hour ride with much of it mixed between tempo and riding relatively hard, sprinkled with multiple efforts of 3-5 minutes where the inquisitor is really turning the screws and a final few kilometers where I would literally be turning my lungs inside out, i.e. just about when Jens would be saying "shut up legs".
My three goals for a race would be:
1) to have the required endurance to ride 60 miles and have enough in the legs remaining for a final kick.
2) to have enough sustainable power to hang with strong riders (great drafting and wily paceline skills can sometimes be a substitute unless there are extended climbs or lots of smaller steep selection climbs).
3) to have enough top end to hang with any attacks or create my own, and have enough repeatability (matches to burn) so my legs didn't fizzle after one or two strong surges.
For a TT I'd focus on #1 and #2 (especially #2), and ignore #3 altogether.
I like to think of fitness as a pyramid with aerobic conditioning on the bottom, threshold power in the middle, and anaerobic capacity on the top. Aerobic conditioning takes the longest to develop and provides a foundation for all else. The closer we get to the top of the pyramid the skills are more quickly gained, harder to hold onto, and more quickly lost as well. With this in mind I'd work on a solid base and then focus on developing the race specific skills as I get closer to the event.
Weeks 1-2 I'd want to to be on the bike 5 days/week and have a few end/tempo rides ~2 hours. Consistency, not intensity is the key here.
During weeks 3-6 I'd transition to developing power, doing sweet spot intervals 2 times a week. Either two efforts at about 18-20 minutes, or three efforts at 13-15 minutes after a 30 minute warmup at endurance pace. When I start the VO2 work in week 5 I'd drop one of the sweet spot sessions.
Weeks 6-8, I'd add VO2 work. Some like 4 minute intervals, some like 5 minutes, some go even a little longer (crazy people). They can be as short as three minutes and as long as 7 or 8 minutes. I've found 4 minutes works well for me as I get a sufficient workload, but I don't start hating life on the bike. These are tough. I would not do this sort of intensity more than twice a week. And considering I'll be doing some VO2 work on my long ride in weeks 7 and 8, I would only do one additional structured VO2 interval workout (for a max of 2 sessions a week... this is 90+%MaxHR territory!) VO2 work needs a healthy warmup, I typically do an hour of endurance and one effort where I wind up a big gear till I spin out beforehand, pedal easy till I'm composed then prepare for entry into the pain cave (that's somewhat evident on the 2nd chart below with the two spikes at the 25 and 30 minute markers).
Weeks 7-9 I'd probably add one session a week where I did 5 or 6 two minute anaerobic intervals, with a few minutes rest between each rep. I'd basically just go as hard as I could go keeping in mind I want to try and be consistent through all my efforts. Again, I'd tailor my schedule so only two days of the week featured work into the 90+%MaxHR zone.
From weeks 4-8, I'd want to add one 3-4 hour ride every week. The first one or two at endurance pace is fine, but as the training progresses into weeks 5 and 6 start adding a couple 15-20 minute segments in the middle of the ride at sweet spot (~90%FTP, or in HR terms 75-85%MaxHR). The last two long rides at week 7 and 8 I would want to be doing some of the ride at tempo, two or three 10-15 minute intervals at threshold (or sweet spot, ~90% effort), and one or two 4-5 minute efforts at VO2 output, deep in the pain cave. I'd want to come home from these last two "big" rides completely destroyed.
This is a relatively easy 10 hour/week kind of plan. It won't get anyone to the pro's but something similar would be enough for me to have fun and be somewhat competitive in a low Cat race. The schedule assumes I'll be on the bike 5 days a week with two hard days (threshold/VO2/anaerobic intervals, or one of those plus a long ride w/intensity) and two endurance/tempo days. An easy mistake would be to ride those end/tempo days at the top of the zone. Try to vary the pace on those "slow" days.
Because it's a pretty short schedule I wouldn't take a whole rest week in the middle as some coaches may recommend but I would take a few easy days around the 6th week just to bring about some freshness.
My last "big" ride (long + hard) would be 10-12 days out from the race. I'd still however continue my anaerobic intervals into the early part of the week before the race. Anaerobic fitness disappears more quickly than aerobic fitness and for a race decent anaerobic capacity is essential to be competitive.
The week before the race I'd take relatively easy, doing some 1-2 minute all out anaerobic efforts early in the week, but I wouldn't want to come home from any ride this week beat up. I would ride for an hour the day before the race with one or two hard 1 minute efforts to open up the pipes. Assuming the race is a Saturday, Wednesday and Thursday should just be easy pedaling. Nothing you do in the last few days will have any positive effect, it can only make you slower.
Disclaimer: A lot of folks poopoo HR as a training method, mainly because of it's inconsistency, it's essentially useless at for measuring any short effort (it would take a full two minutes for HR to catch up during a two minute interval rendering it moot), and the fact HR rises slowly over a consistent effort and riding at a steady HR actually means completing an interval with descending power output.
I've attached a chart I made of how my HR operates over 20 minute intervals (sweet spot/sub-threshold), and 5 minute VO2 intervals. One can see as my power output remains steady, my HR rises, and in the case of the VO2 interval, quite dramatically (personally I would do those at RPE). When in doubt always do the first interval slightly easier than you think, especially when doing VO2 work. Some coaches even refer to the first in a short interval set as a throw away.
See chart below for recommended rest between intervals. There's all sorts of interval protocols, but these are two simple types that do the job.
I'm not advocating this plan, it's off the top of my head, but it may help give an idea of how to ramp things up. I'm sure there's something in there that doesn't line up properly but don't over think it, just ride as much as you can, ramp up the intensity over the several weeks leading up to the big day, and taking the week before relatively easy. Eat well, and get lots of sleep. On the big day, follow wheels and let others do the work, keep your nose out of the wind, and keep a handle on your personal limits.
I'm certainly no expert but maybe some of this will be helpful.
