how to sim. hills?
 
Where I live (south jersey) it is flat as crap. I mean flat 10ft elv change in 1/4 mile is a big deal. My ears pop when I cross big bridges no joke. How would I go about simulating riding on hills?

Low cadence. High resistance. Zone 3 heart rate.

Find relentless head winds.

thanks headswinds i've got in spades. Is that bike plow real?

Above are good, but also: Take a weekend or two and drive to some hills. Seriously. You're not that far from some for-real mountains, get up there and ride a few.

I have been riding a long time and I know that headwinds do not equal climbing. I can always squirm myself into a more aero position on the bike, but no amount of squirming makes me weigh less.

I have a clogged terlet that would beg to differ

Exactly. Try adding some extra poundage to the bike, OP.

I've used a cinder block, my trainer, and a big gear to simulate a long, steady climb.

While a hell of a workout, it technically doesn't simulate climbing. A long time ago asgelle posted an excellent article that showed muscle recruitment patterns and they were clearly different from actual climbing. Apparently pedaling against a braking system is different from being actively pushed backwards like with headwinds* and hills.

*I agree with Mollusk that headwinds do not equal hills. I've done some damn windy TTs and they weren't anything like riding up to a ski resort parking lot.

caloso 12-18-09 07:11 PM

I think you're right. It's more about developing seated, low cadence, high torque. But sometimes it's all you can do.

brianappleby 12-18-09 07:24 PM

Do you race on hills? If not why train for them?

DrWJODonnell 12-18-09 07:28 PM

Go west into PA or north in Jersey. I used to train those roads all the time. Headwinds are a rough estimate, but you need hills for hills and there are a bunch not too far from there.

I didn't this year (I do tri's) but I'm starting to travel some with a buddy when we race together and those have hills and I get dumped in about 2 sec when there is a 3 percent grade or more. I don't want to be lighting just keep it respectable

If someone has it handy, please post this study, or some direction on where to find it. I was under the impression there was not real difference.

If this forum had a search function I could find it...asgelle and terrymorse might have full text.

This is the closest I could find and don't have full text.

Muscular activity during uphill cycling: effect of slope, posture, hand grip position and constrained bicycle lateral sways.
http://www.ncbi.nlm.nih.gov/pubmed/1...m&ordinalpos=2

The gist of it was that the EMG readings from the 4% incline on the cycling-treadmill were much different from the 4% incline on the ergometer -at equal wattage. Pretty weak I know, if you find more please post it here.
