- We took a trip back to LA to do Aero testing with Jim Manton from Ero Sports erohighperformance.com/ to try and find some speed before PTO US Open and 70.3 World Championships.
The main two things we tested were Holly's aero position and her sleeved. triathlon race suit vs the swim suit. Watch the video for the results.
Special thanks to Jim Manton for taking 2 days to test with us. Check out his youtube channel @fastorfiction to see if the latest trends in triathlon areo dynamics are actually fast or if they are fiction.

Jim is great to work with and well worth the investment.

These gains are significant and real, because you clearly wanted to hear “nope, swimsuit is just as fast” and “nope bottle in front looks stupid and is slow.” The micro-gesture of disgust and resignation when you admitted both were faster was just delightful.
😂
Quickly becoming one of my favorite triathlon channels. Keep pumping out the episodes, they're awesome.
thanks so much - we will!!!
Great video! Thanks Holly
Great insight, enjoying the channel. Such a bonus to see professional athletes laugh and enjoy their lives.
nice video! rooting on your next race!
I love this! I’ll be looking for you in your next race. 😉 I just subscribed to the Ero Channel when I watched the bottle in kit test.
Really enjoyed that, Good work.
🏴
Ahhh thanks!
Hey! Checking in from Somerset,UK. Your American dream looks phenomenal. Best wishes for the seasons races 👊🏻
Wooop woop!!! We’ll be back in Somerset for our wedding in September - pray for good weather!!!! ❤
Super great vibes 😎
I love your videos Holly and I especially like the you vs. your partner confrontations!
Thank you so much!!
I do the same thing with swimming - I swim long sets at race pace and have a beep timer at that time at 100yds. I'll change one thing about my form and see if I start beating the timer at the exact same effort. I can tell exactly how high to hold my head, where to enter my hands, how much to kick, how deep to pull, all to maximize the speed for my effort. It works really well!
Woah 👏🏼
Yea, pls tell him to put out more work! And you too!! Great video
We will!
Well this is the most unnecessarily unpleasant comments section I’ve seen in a while. Good on Holly for dealing with it with a good sense of humour. Really enjoying this content, keep at it :)
Interesting and I'm really looking forward to seeing you race this season...although, you won't be quite as recognisable without the swimsuit :) the bottle down the kit is a funny one; every test I've seen shows there to be a real advantage. I'm doing Barcelona in September
so I'll have to test it, but I'm half hoping it doesn't make me any faster coz paying for a technical Huub tribute and then sticking a bottle down it just seems wrong :(
Haha right!!! If you have a well fitting trisuit jamming the bottle down is a stretch!!!!
Curious to see the comparison of testing results from sea level to hear in our lovely "triathlon bubble" city! LOL. Bring the Noise Holly!
Very nice video Holly! I love seeing experiments like this and what we learn from them! But I must say, I'm not sold on the bottle between the chest and the shirt. in addition to the "look," I would need to test for comfort for long distances. Curious what your nutrition setup will be for the new Trek Speed Concept given the many options out there?
Wierdly you really don’t feel it while you’re riding (mine was empty) but yeah it looks ridiculous !
The real world aspect made this super interesting! Question? - as pros are so dialed in, did you find the bottle down the suit so much of an improvement you would recommend it to ‘good’ age groupers?
I honestly think so! Check out Jim’s channel - for higher up positions Jim’s seeing there are actually bigger gains for a bottle down the chest than I got!! 🤯
i wanna know how much watts difference the trisuit had over the swim suit. thanks
I was really looking forward to this episode! Interested to know why you chose those aero bars and not other ones? Wattshop, Aerocoach etc.
I started with aerocoach but i couldn’t get the reach i needed - sync just looked like a super sleek and very adjustable option without being clunky - and I paid FULL PRICE (despite giving the all the cad files and blueprints for the new speed concept) - so it’s as real a review as you can get!!!! 😂
What about the swimsuit in itu races? Do you think they will change?
Also, it may be faster on the bike but what about the run? It is much more comfortable running without tight material around the quads I find.
No, cuz they are drafting on the bike
I couldn’t love your videos more ❤ Sean does such a great job with the videography and then your chemistry is just 😍 … marry that guy 😅
Great video! Excited to see you race again!
❤️❤️❤️❤️
Super interesting video!! Did you show any aero gains with the calf sleeves?
Marginal gain but still need to test some different brand calf sleeves.
Awesome video, thanks for sharing. Quick question. Is the bottle down the suit empty or full?
I will try it empty since it will be difficult to take in and out during the race.
@@passionprojecttriathlon would be interesting to test both empty and full (and see if the full, being heavier, is more advantageous due to increased rolling efficiency when at speed)
Great video, thanks for sharing! Did you test different size bottles? Sounds like most people are faster with the 1.5L size, but it’s so big and bulky!
I tested a 750ml bottle and honestly that was a struggle to fit in there - I wouldn’t go any bigger for me - but I honestly didn’t feel it when I was ridding - even though I thought I looked ridiculous!
Get a life
What does the acronym at the end …. CRA? Stand for? Something about aerodynamics factor?
CDA - coefficient of aerodynamic drag
yep - it is all about AERO
Holly enjoyed the video. What aerobars are you riding these days. Did the angle make a big difference?
It's hard to tell if the angle made a big difference. A small drop (5mm), a little more reach, and a slightly more angled bars, all combined made a significant difference for me.
What about gains regarding calf sleeves ?
Marginal gain - but I still want to try out different brands.
Maybe it's just me, but is her cadence really low? I like to train to 85-90/minute. I don't actually run or swim, so hey.
How about calv sleeves ?
Very small advantage for me, but I would like to test a few different versions next time.
You two are too cute 🥰
Rather than that 2 day drive - with bikes and holly flying separately, was there any thought given to … simply paying for Jim to fly to Boulder with his box of testing goodies and a laptop for a day?
Jim’s time is more precious than mine and definitely Seans 😂
6:53 - 7:05 She looks lovely riding with a swim suit.
Holly what hairdo was more aero? Can you believe the couple mullets in the tour? 🤭
A plait/braid! I’m destined to look like a little German child 😂
@@passionprojecttriathlon you are going to rock it! I saw it in your video but I didn’t know if that was deemed the best option.
Nooooo, bring back the swimsuit!!!
Time to start a petition to PTO to make some uniform rules - all women have to wear swimsuits! 🙋🏼♀️ you’ll have my vote!! 😂
Dang, i think pto should ban trinsuits and make swim suits mandatory for their races, dpnt care even if men would be nadatorynto wear Speedos... It just makes better tv... 😅 No, but all seriousness, good to see more optimiced Holly on the race circuit foreseeable.. cant wait how it relates, i assume the savings will be around 15-25w at racespeeds, which is 💥
Pop in the suggestion box to @ptohub 🙋🏼♀️ 🙏🏻 gotta give the viewers what they want!!!
I was so hoping you’d report back that the bottle made you slower-looks like you were too. It looks so silly, more so on an AGer like me than a pro though.
It looks so silly! But unfortunately it makes you faster - and by a substantial amount!!
She looks spot on with her bike fitting.
The be honest, i am quite shocked how an athlete of your calibre did not use an aero suit for years.
Maybe you should call up Sebastian Kienle so you safe some time testing 😉
Chain preparation, tires and pressure seem to be a easy gain as well.
Ps: I hope the bottle in the suit gets banned. It looks silly and in case of a crash this cannot be good.
It would be fine with me if the videos were just Holly giggling the whole time!
Ha!!! 😂 nobody wants to see that!
Skin is Slow, Fabric is Fast, but Wrinkles are Worse
I used to really like Holly...used to
I was praying to the gods that the swim suit would be as fast as the trisuit. Now sad. 😥
Me too!!!😢
ok, not preggy...its just a bottle🙊
🤣
These people act like riding a bicycle is some type of skill like it's not hard to be fit and be good at riding a bike fast
Not when you’re Taylor Knibb - we gotta do this stuff to have any kind of chance of catching up!
Why would you say that? When you look at the performances and the efforts these athletes put in, don't you realize it's real hard to be getting faster and faster on the bike and then be able to run even faster half marathons and marathons off of it? I don't like the bottle thing but find all other aspects fascinating.
I was waiting for any useful AERO information but wasted 13 minutes on my life
Chuck a bottle down your chest and skip the swimsuit … your welcome 😉 sorry I can’t give you those 13mins back though!
It’s all bull sh#t
