...on the bike and what was your bike time? Did you try and maintain a certain cadence? I read somewhere to keep it around 90. Curious.

IMWI 2007 

5:25:00

20.7 mph

96 Cadence 

I didn't have a power meter or speedometer, just  cadence and HR. Kept my HR in Z-2 for most of the bike.

Here's my info for IMAZ.

Cadence: 87
Time: 5:45:27
Avg speed: 19.45

My power numbers for this race were useless because when I replaced the head unit of my PT, I forgot to set the auto-zero option for torque. All my numbers were skewed high until I figured that out.

IMFL - 5:17, 21.1 mph, average was around 100 (don't have an average on my cyclometer, it is just what I always maintain my cadence above).

Chessieman aqua velo - 5:10, 21.7 mph, cadence also in the 100 range.

I've always been a high spinner, going back to my road racing days.  It's just what feels right for me.

I think the number that matters the most is your HR. . .keeping that in check is the biggest thing to remember. . everything else will fall into place.

For my first IM this past June, I asked a friend of mine about mph and time on the bike and he said (Kona qualifier many a time) that I don't even need a computer on my bike. . just watch the HR, keep it in the zone and I will be fine. . .and he was right.

Oh, and he doesn't have a computer on his bike. . does everything by HR during the race.

It's probably fair to say that I have the best IM bike around these parts, sorry Rick , but I am a gear masher. I push big gear at a cadence well below 90. This can be very problematice for many athletes as it can ruin you for the run. For me, it doesn't, but that's just me. My coach has tried to get me to spin to 90 in training, but I don't use a meter and get tired of counting. Next season, I may try and improve my cadence. Having said that, if you can train to a 90, do it, it does seem to provide a great balance between power and efficiency.
I soley use HR, which has it's issue's but works well for me as statyed int Tell's post above.

That makes a lot of sense, Tell3131....I actually am a lousy guesstimator on speed. I actually used HR and cadence combined as biofeedback during my first HIM. Worked well for me! Will use the same feedback along with perceived effort for my first IM.

Wondering if anyone else uses perceived effort or combinations of feedback?

Even though cadence is been suggested as 'optimal' between 80-110 rpm, its influence with your ability of riding fast or posting a solid run is not directly related. The data collected from several IM finishers suggests that speed has more to do with training, aerodynamics, pacing, nutrition and how your rpm matches your running cadence. Furthermore it is normal for an IM power file to show a decreasing rpm trend throughout the race and this makes sense as rpm is more correlated with your ability to generate power. IOW the more fatigue settles in the harder is to keep a high cadence. (you can find studies about this online)

That been said there are certain benefits to avoid very low/high rpm as the energy ‘cost’ from each can affect your TRIathlon performance in difference ways. If you have access to training with power, you can test this and find your sweet spot. You can do one ride and make a point of riding at certain intensity/rpm and do a short brick run and then review your file and analyze your energy expenditure (kJ), rpm avg, power, torque and how did it feel for you during the ride/run etc. Then repeat with a different rpms (same intensity), within a few weeks you will find your specific sweet spot! You can do the same without a PM but it won’t be as clear and it will take you a bit longer but it is great to test this in training.

Personally I don't buy into the optimum cadence theories. IMHO, the best cadence is the one you're comfortable riding at. I just happen to ride at a high cadence. Always have. In a standalone TT my cadence will usually be in the 105-110rpm range.

For real! You think I wouldn't have gone sub 4:45 at this years IMFL?! LOL! TYou have alot to learn about IM racing! Comparing IMFL to Kona or a windy IMAZ is a Joke! I'm going to assume you can read a course elevation chart, Rick. I would have killed it at IMFL if I can go 5:03 at Kona, bud. I was the 99th fastest bike split...in the world championships, biatch!
You need to step it up if you want to make comments like that, and you are way far way. Sorry.

I'm putting my money on the guy who did 9 hours 40 minutes in Kona over the guy who did 12 hours 30 minutes in Florida.

What's the bookie's number????

Hey, I never said I was the undisputed cycling king, so don't jump down my throat, last time I checked my screen name wasn't "runatlanta" ........ just showing that there are BTers who've gone faster than Bryan! Tongue out

So this just ain't true ....

It's probably fair to say that I have the best IM bike around these parts

You threw it down, I picked it up and gave it back.  You didn't say you were the best IMer around, you said you have the best IM bike.  And while I certainly don't, there ARE people on the site who have gone faster.

The key is he said IM biker, not just plain biker. And I'll still put my money on the guy who did 9:40 in Kona over the guy who did 12:30 in Florida any day, since he obviously knows how to ride a bike in the context of an IM race a whole lot better.

And go look at the fastest AG bike splits from FL, AZ, and HI ....... you'll notice that FL is not as "fast" as everyone seems to think it is.

I never said it was about me versus him.  Just that he is not the fastest BT IM rider (nor the fastest BT IMer thank you very much, there are others such as Joel that have the same sort of times ......)
