Subject: Ride IM on a roadie and still have legs for marathon???
I am debating putting clip-on aero bars on my road bike for IMAZ, but will consequently get a bike fit tailored to the aero bars, thus making it less comfortable to ride in the drops. But I love riding in the drops and having the freedom the multiple hand positions of a road bike offer. My main concern in riding a road bike without aero bars and the more forward position is that it will trash my legs for the run. Has anyone done IM on a road bike without aero bars and if so, how were your legs for the run?

I did a roadie sans aero bars for IMFL last year. My legs were, as expected, tired. But I can't say how tired they would have been if I had aero bars.

Last month, I put clip-ons (draft legal, ie. shorter than your usual aero bars) onto my roadie and like the extra position. I didn't adjust my fit. I just did a HIM with my new clip-ons and I think my legs were a bit fresher for the run leg all things being equal. Hard to say how much though. Though, I did notice that my back ached a bit more with the clips-ons, but that might have been because I only installed the clip-ons a few weeks ago. Overall, I think the clip-ons were a good addition.

My suggestion is to get some clip-ons (perhaps borrow a pair?) and try them. See if they work for you or not.

I use clip ons on my road bike. My fit is for the bike without aero bars and I would say that that I used the aeros for about 30% of my IM. Wales, a very hilly course. The legs felt as good as you would expect after 112 miles on one of the toughest bike courses in the world.

Train for what you expect to expect on the day. If you think you will spend 90% of the course on the aeros then you should train on the aeros and have your bike fit to suit. How your legs feel after your ride will depend on the effort used on the ride.

Either position will be fine towards the original question so long as it actually is a good fit for you. The trashing your legs is from riding too hard, not roadie vs aero. And by nature of it's size, an IM bike leg is quite likely to be hard for a lot of people even though it's at a rather low effort.

If your bike fits you, and your ride within yourself, take in proper hydration and nutrition, road or tri bike both will work. For most a tri bike you will go faster with the same effort due to improved aerodynamics. Faster bike split equals less energy used on the bike.

Neither will trash your legs more for an Marathon if bike fits you well and you train on it.

I feel more comfortable riding my tri bike than on my road or cross bike. If a tri bike fits you correctly, your skeleton supports your upper body.

I've had two friends do IMAZ on road bikes.  They did fine.  They didn't break any records, but they finished well

The myth that a tri bike helps save your legs for the run is just that... a myth.  A tri bike is more advantageous for one reason: aerodynamics.

Getting a good fit is paramount.

I'm doing my first IM next March - on my roadie without aerobars I think.  I'm happy and comfortable that way.  I get no back issues.  I'm not fast it aint gonna make a jot of difference if I'm aerodynamic or not!

If I get the IM bug and love it so much I sign up for more then I'll invest.  But for now.  I'm rolling with the roadie.

I used my roadie on my last IM and I was trashed when I hit the run...

 

But that's because I was undertrained and had nothing to do with the bike.  The only reason I chose it, is because of my lack of training on my TT bike which would have me sitting up most of the time anyway.  If I'm going to sit up, might as well be a little more comfortable doing it.

If the bike is fitted for you, you will be fine.

As a side note, I know they are pros, but the TdF riders average almost 100 miles a day for 21 days (with two rest days).  I know they are not running after, but they save their legs enough to do another century the next day, and the next, and the next, then a time trial, then another century.  etc.

Aerodynamics are still aerodynamics.  Fast or slow... it's still science.

I’m a 240lb man, and I run relatively long distances. How would you recommend training for marathon and IM distances as heavy as I am?
