Speed with backpack vs. no backpack?
Does anyone train on their commute with a backpack and have comparisons of similar training without the backpack?
I don't have much time so I train while commuting, but I am carrying shoes and some combination of clothes, lock, food etc in a backpack.
Just wondering what might be the non-backpack equivalent of a not-so hypothetical 26 mph for 6 minutes with a backpack.

backpack is a huge drag, literally.
on a day when you're not commuting, why don't you just go time yourself with and without a pack? it will be hard for us to say without knowing your position, power and wind.
you are losing a bunch of speed (or using quite a bit of extra power).

I do a lot of my training on the commute with a back pack. It's added weight and drag and has a noticeable effect but I've never tested exactly how much effect it has. I usually do wattage based intervals so I never pay any attention to speed.
It would make for an interesting experiment though.

What?
It would be more useful to me I guess because I don't have any way to measure power (I don't trust Strava power on the flats with a backpack haha)

Fwiw you should start keeping some shoes, maybe even clothes at work, and try to eliminate the need for it.

I leave shoes and pants at work. I bring a shirt or two and use a 1lb backpack or musette bag.

Been considering it - carpool a whole load of clean laundry and groceries in every Tuesday or something.

At my former employer we had a shower room and lockers where I could keep a week's worth of clothes. I'd drive them in Sunday evening and take them home Friday afternoon. At my current employer we have showers but no place to keep clothes, so I just keep my shoes here and bring carefully folded shirts, pants, etc. in a small REI daypack. It's not ideal, but it works.
And obviously, the higher intensity interval, the more annoying the backpack. 2x20's? No problem. Tabatas? Ugh, problem.

Isn't this the same kind of argument as a heavy vs light bike? You simply go slower for the same output with a heavier bike or heavy pack. Speed in this case is irrelevant, it's the work that matters, so use an HR monitor or go by RPE.
And yeah, riding with a bag sucks. I always found a well-secured messenger bag more comfortable than a backpack, but I also have a place to keep shoes, pants and toiletries at work.

I like backpacks better than messenger bags.
Now we'll never know.
Also, 18mph. Or 5mph. ****. I dunno.

Edit: I guess I should just get in the wind more in my 9 remaining practice races and I'll know then.

Never understood why people think that's an effective way to train. I've had people ask if i'm riding gatorskins to make the ride harder. I ride them because i don't want to flat when i ride through broken beer bottles.

Agreed, purposefully riding a heavy bike, etc as a way of "training" is like reverse motor pacing and makes no sense.

I tend to use bike commutes as endurance rather than interval training.

Assuming for the sake of argument that I'm wrong ... maybe it's better to train carrying a bit more weight and air resistance - or would that be unwise for some reason?

My issue with backpacks, at least the ones I tried, was the top strap thingy would get caught in the back of my helmet. I like the weight lower on my back than I could get with a backpack while keeping it securely in place. My Timbuk2 bag, using the chest strap, would never move if I loaded it properly.
Of course, YMMV and all that, personal preference, etc.

I commute with a backpack - long commute (22mi each way), so aero efficiency matters. I used to use a Mountain Hardware Paladin which was nice inasmuch as it is waterproof and tough, but it had a big flat top that sticks high into headwinds, as well as a tall, narrow profile that catches crosswinds.... not to mention the obnoxious aluminum zipper pulls and grab handle.
Once I moved to a Koki Vespa, I noticed a huge increase in both riding comfort (it has a mesh stand-off style suspension) and also aero drag. Also, when the pack isn't fully loaded (just a laptop and some basic essentials) I use a little velcro loop to batten down the front pocket to the grab handle and improve that headwind profile a bit:
I do find that when i ride my other bike with a side pannier, it feels draggier in comparison, but it is the most comfortable, having nothing on my back at all. Still, for my long commute, I'd rather just go faster.

I agree with this - I shower at work so no worries about sweat, etc... and every couple weeks I ride the bus and bring a duffel bag full of clean underwear, socks, a few undershirts, and a few sets of my primary outer clothes - my office is non-customer-facing so no need to worry about a fresh clean suit - I just wear the same pants and work shirt several days in a row. It's nice to have all that stuff at the office and not have to haul it daily on my ride. I do frequently haul my laptop though, since I may have to do something urgent from home, or maybe just opt to work from home many days.
