UncleFred said:Thanks for taking the time to comment, I have a few questions....
1. I can do a long ride once a week, I have between 4 & 5 hours available but what sort of pace should I be looking at? I like to ride at about 80%MHR, I feel like I'm getting a benefit at this pace, but should I be slowing down a little?
2. I can do the long rides on an almost flat route, but if I wanted I can put in up to 8 short, steep (20-25%) climbs on each lap. Is this worthwhile doing or should I just stick to the flat.
3. Most of my climbing training is off road and on my MTB, that way I can get the climbs in in the available time that I have. Is this riding beneficial or should I switch to my roadbike and try and climb on that. The only problem is the paved roads that are easily accessible from my house are very rough, concrete roads and I don't want to trash my Road bike.
4. Looking at the profile of the Etape, the climbs are long and not as steep in comparison with the short steep climbs that I do. Will the endurance training be more beneficial to me to complete these climbs or do you have any suggestions for improving my climbing. IE get off the MTB and do more work on the Roadie..I've been working on the principle that the short steep climbs will improve my power.
5. Basically it's the climbs that are worrying me, should I stop worrying?
In consistency with what the other posters were writing, I'll also explain the long ride as opposed to discussing an exact schedule.
The idea behind the endurance ride is to build your aerobic system and getting your body used to putting in the time. If you don't do this, no matter how much climbing power or sprint ability you have, you'll run out of gas. Hence, for that one ride a week, enjoy yourself and don't worry about power, speed, and heart rate. 70 - 75% MHR is fine for that ride. If it goes to 65%, don't worry about it. If it goes up to 85% at some point, don't worry about it. Just try to make it an enjoyable nonaggressive ride. If you're sitting at 80+% for a long duration, pick a lower gear so you're not working as hard.
To keep from getting injured or over training, try to build each week at 5% or less total time in the saddle. Keep in mind that a 3-hour ride at 4% increase 3 hours and 7 minutes so it isn't an exact science and it's only a general rule, not something that requires exact calculations. The goal is to have your long ride be of a minimum of 75% of the total length (and time in the saddle) at around the 3 - 4 week range prior to the event before tapering your training. To get to that length, you can do the math between now and then to see how long your rides should be at this point with about a 5% increase per week.
For us "less then elite" athletes (I won't categorize you in there but I'll definitely speak for myself), I've found that, following a published training program or not, the best thing I can do is take the entire last week before a major event off completely. Drink a ton of water that week (I mean more then you'd like to) and eat what you want. It's what I've done anyway...
Most of what I've just written is found in just about every endurance training program book.
In my opinion, there's nothing wrong with training on your mtn bike, however I'd have one concern, your body will also have to adapt to the position of your road bike for the event. If you train exclusively on the mtn bike, you'll probably get stung on that point. Also, on road bikes a person tends to just "go", but mtn bike riding can have a lot of starts and stops. At minimum, you'll want to ensure you're getting quality time in on the road bike.
Your shorter hard climbs are a sort of interval training. That's a great part of your training program. However, one trick I stumbled upon that improved my interval training massively was adding one swim day of, say, 45 minutes a week. I'm a crappy swimmer (which is probably part of the reason it's works my heart so well is that I work too hard), but the controlled breathing of every third stroke and the racing heartrate made a HUGE difference in just 6 sessions of once a week.
Once again, I really wish you good luck. I'd have to cross an ocean to join you so I'll just have to stay jealous.
