Equally awful?
This is one of those cases where it’s just time to suck it up and get running.
I run faster off the tri bike than I do off the road bike. My hamstrings feel fresher off the tri bike, and my calves are usually tighter though they usually feel less fatigued as well. Running off the road bike, my hip flexors are tighter and my quads aren’t as fresh. As a result, I run with my hips much more closed, and although I can still do an adequate job of driving the knee forward, I don’t get as much extension as my leg moves toward toe-off.
This seems a bit counter-intuitive, but I think it has to do more with the actual muscle recruitment than the position I’m in on the bike.
I run like a penguin for the first 5-10 minutes off a road bike. waddle, waddle.
Off the road bike, I just run.
the question as stated isn’t really coherent.
the way some people are positioned on a road bike isn’t any different than how some people are positioned on their tri bikes.
there is nothing inherent about the frame that will change how you run.
don’t expect any miracles. running is running.
The relative position of road vs bike is most important, but also the ride characteristics will play a part too, cet par. Hard to say what the difference will be though Without specific details
have you ever noticed how much pro ironman runs have sped up since the days of people riding aero on steel round tube road bikes with aero cockpits bolted on?
what is it, 0?
I don’t know if that makes sense. Your hip angle shouldn’t change that much. You ought to be largely just rolling your position forward.
Also, look at the ITU pros. They are blazing off road bikes often slammed forward with shortie bars. Doesn’t seem to faze the Brownlees, Gomez, Findlay or Snowsill…

maybe they’re just biking harder and running the same…
i haven’t actually ridden a tri bike yet so i can’t comment, but i do ok running off my road bike.

I’ve only had a road bike since March. Before that, I rode a tri bike only for about 5-6 years. I got very used to putting power to the pedals from the aero position, and the road position has taken some getting used to. So far I just haven’t been able to replicate my tri position on my road bike, although I’ve come pretty close. Part of the problem is I just don’t have hundreds of dollars to throw around to find the right combination of stem + aerobars. Can you explain what you mean by “rolling your position forward?”

Ideally, when you go from an upright road bike position to a flat, aero position, you achieve it by rotating your body around the bottom bracket, instead of just closing your hip angle more.
Its rare that you can totally achieve that with aggressive positions, but you want to try. This is why TT bikes have steeper seat angles. Low the bars and move the seat forward and you are rotating your whole body instead of just your upper body.
the idea that people would run faster off of a TT bike is based on one study that imho didn’t really demonstrate this to be true, and since people are often in TT positions on their road bikes, and people are often in ‘road’ positions on their TT bikes, the issues gets very confused.
I think you can be confident your running will be as good (or bad) as ever on any kind of bike, as long as your position isn’t bad in some way, biomechanically, for you.
