I did a Duathlon yesterday – 5k run, 25k bike, 5k run. My bike has flat pedals with strapless toe clips, so I just wore my running shoes for the whole event. Almost everyone else was using clipless pedals.

If I switch over to clipless pedals, I’d need to change shoes twice during the event. I think that would cost me about a minute in total. Would I make up that lost time on the bike by using clipless pedals? I was just over 50 minutes for the bike leg, so I’d need to be 2% quicker for it to be worth it.

Did my first ride with

Did my first ride with clipless pedals yesterday, my initial impression is pretty positive.

Got some Shimano Click’R pedals (the clipless pedals for noobs). Surprised by how much “float” they had, didn’t feel as locked in as a thought. Unclipping was easy enough, clipping in was a little hit and miss – usually it was taking me 2 or 3 goes to connect properly. Should get better with practise. The pedals have a reasonable amount of platform on them so I can still get started without being clipped in.

Looking at my Strava for the ride I was a little quicker than previous rides, although that may just have been the weather. Too early to draw any firm conclusions.

As sporting activities,aren’t all three equally pointless,(or valid ).I hope you’re joking,but fear you’re not.

Yeah – trainers are just as

Yeah – trainers are just as good – that’s why all the pros use them for testing…

Clipless, tri-bars and some advice on your aero position and you’ll take minutes off your time.

Don’t get me wrong, clipless pedals have many advantages, just speed is not one of them.

My mate done the same and set a PB 🙂

I think if your pedaling style is good flats are just as efficient if not better, without locking your feet (knees) to a more fixed position 🙂

Yes, that’s probably the way to go first. You can pick up a decent set quite cheaply from Planet X or ebay.

One thing that can be slightly confusing with this is the style of extensions that you get (the actual protruding aero bars). As per the links, they can either be pretty much straight, therefore pushing your hands out front, or curved to bring your hands higher. The current thinking seems to be that the ‘Preying Mantis’ position is actually more efficient. Of course at amateur level the gains will be tiny, and overall comfort is more important.

Regarding footwear – I suppose for shorter events (duathlon, sprint triathlon), then trainers would be fine, but if you wanted to do longer events then I think stiffer soled shoes would be more efficient and comfortable. A good compromise, pedal wise, would be hybrids with flat on one side and an SPD fitting on the other. Decathlon do a version for about £25.

Aero is everything!

I don’t agree with that analysis. Just pressing down from 3pm to around 6pm wastes alot of potential to apply more to the power stroke. Pushing over the top of the pedal stroke and pulling back and up a little increase force over a wider arc. I personally found it reduces particular muscle stress whilst increasing cadence.

I spent a whole winter on the turbo learning to improve my pedal action and cadence.

I may not be more powerful in higher threshold, but I can sustain my power for longer

It’s an odd article if it is intended as a scientific analysis. The terms “maximum power” and “maximum efficiency” are used interchangeably. They aren’t the same thing. Not even close! For me, pulling up is more about using different muscle groups to aid endurance. I live in France, and my cycling is all about big climbs. If I’m grinding away for half an hour or so, I suffer less fatigue if I use more of the pedal stroke.

tri bars will save you at least a minute over 25km, it’s the single biggest thing you can do to make yourself more aero.

 

At least at first, save your money on pedals/shoes and buy some tri bars and if you have the money, an aero helmet/skinsuit etc

Using a set of tri bars will be by far the biggest bang for your buck. I assumed you were using a TT bike already.

I have a feeling there may be a GCN video where they experimented and found, counter-intuitively perhaps, that on an indoor trainer they were faster on flats.

 

But I may be misremembering.
