Mount/Dismount with Road Shoes

Get tri shoes. Leave them clipped in.

That would be much more efficient. Otherwise, seems fairly sound to me.

What I do is I mount with my shoes on and dismount with my shoes off.  It doesnt have to be a one way or the other for both.  With your T1 time, it sounds like this would work for you. 

Yikes, I watched some videos of this on youtube.  Impressive, but I can't imagine being able to unclip my left that effortlessly.  I understand this comes with practice, but are they using some sort of pedals/cleats that would make this easier? 

I race CX and am good at doing CX mounts and dismounts.

I do CX type mount in tris but I take a more conservative way to dismount...unclip my foot before I stop, then lift my leg over and run off. My MTB pedals and my road pedals are quite different in how easily it is to get in and out of.

If you aren't 100% confident in your mount and dismount method don't do it that way but a way that is safer and you are sure you can do. In a race you will be going harder than you do while doing it on your every day life plus depending on your swim wave and time the mount line may be super crowded. For some more focus may help them do better others mess up. Falling, crashing, going off the course will delay you more than doing it a slightly slower method.

Last year there was a video of women's ITU tri showing the women mount there bikes, so many crashed, went zig zag over the course causing issues with other riders. Most were doing the shoes clipped in method of mounts and these are elite racers.

If you are referring to CX, then I would guess that very few are using Look cleats/pedals since they don't handle mud.  But really any pedal system should be fine for your purposes because the retention adjustment can be loosened up to allow it to come out pretty easily. 

I do this on my mtn bikes because I prefer to come unclipped automagically when I'm crashing.  I have never unclipped accidentally while just riding, but otherwise unclip very, very easily.  In fact, if my pedal hits a rock more times than not that foot pops out.

You describe running and flying mount in road shoes.  I can't imagine trying that in my road shoes.  The cleats and soles are hard plastic or carbon fiber.  They are as slick on pavement as ice.  I could never trust my leap.  And a $200 pair of carbon soled shoes would be ruined.

It sounds like you already do just fine though.  Do you believe you are losing significant time?

I probably should have addressed this initially.  No, and considering where I place, it doesn't much matter.  Mainly, I was curious as to how people were mounting/dismounting when using road shoes and not having them on the pedals before or after.

Again, thanks for the comments.

Go with what works for you, but I guarantee that you're not going to gain back 30 seconds on me in "maintained forward progress".  The key with mounting with your shoes already clipped in is to not even think about putting your feet in until you are fully up to speed and on a flat or slight downhill.  This is where most people fail.  They try too quickly to get their feet in, so they're moving too slowly and they wobble all over the place.

Even if I'm out of transition only 20 seconds before you, I'm not going to lose anywhere near enough speed for you to make up that ground: 20 seconds while you put on your shoes, I'm moving 20 mph, you're moving 0 mph; 20 seconds while I put on my shoes, I'm moving at 17-18 mph (at worst), you're moving at 20 mph.

Do a roll down test on a flat or slightly downhill section.  See how much speed you actually lose from 20 mph during the time it takes to put your feet in your shoes.  It's much less than you'd think and it's way faster than putting your shoes on while doing 0 mph.
