PMSL. That's the problem with getting old, like this guy... @cliffcrocker.bsky.social #webperf

It's been a great couple of days so far at #perfnow, only one talk to go! The speakers are at the top of their game, as are our MCs, clocks and geography not withstanding. My little brain is overflowing.

One of my favourite pictures from 2023 #perfnow @tunetheweb.com @andydavies.me

Interesting to see @timvereecke.bsky.social showing Scalemates performance figures in BigQuery, or as I like to call it "Vereecke in the sheets..." #perfnow

Day 2 at #perfnow I'm going to continue to add notes to my blog through the day stuart-mcmillan.com/blog/webperf...

Ethan Gardner "people don't understand milliseconds", I guess that's true, I mean @tkadlec.bsky.social doesn't understand 24hr clock... #perfnow

#perfnow question for Ines, I noticed you didn't mention prefers-reduced-data do you think it will get traction?

#perfnow question for Ines: Most of the focus (including reporting) seems to be origin or network, less on Scope 3 emissions. Do you see that improving?

@inesakrap.bsky.social asked on stage about crossing dodgy bridges, this is the ropiest one I've been on this year #perfnow

#perfnow another question for Marcy: there are a lot of lawsuits in the US around accessibility, some seem vexatious. Do you think they are helpful?

#perfnow question for Marcy: is the web getting more or less accessible?

Question for Tammy, lots of people are using ChatGPT for research but also now execute tasks, and it's typically not quick. Do you think we sometimes emphasise speed over usefulness? #perfnow

It's day 1 of #perfnow, I am live blogging conference notes here: stuart-mcmillan.com/blog/webperf... @perfnow.nl

We're on holiday in Plockton, on the west coast of Scotland. It's been a great week with a couple of runs so far. I'm still getting over a really bad cold, but apart from that loving life! #trailrunning youtube.com/shorts/s5k3Q...

Storm Amy forced a change of plans for this weekend, so instead of heading to the West Highland Way I decided to do a long (and slow) local route. Furthest I've run for 9 weeks and I could tell by the end! #trailrunning

Beautiful day here in Fife, Scotland. Felt great to have a Type 1 fun run, before a full day of DIY. #trailrunning #running

I love the light we get at this time of year. Just wish I had shot this a bit slower and for longer

Thanks Windows, I'll remember to put something warm under my jacket

We're just back from Chamonix, my first time in 18 years and first time with trail running shoes. And I'm happy to say I'm fitter now than I was 18 years ago. #trailrunning #running #chamonix youtu.be/399mSeALY-E

Chamonix has been everything I'd hoped for, amazing trails and fitness increase without breaking myself. Nice little run in the forest with 508m of ascent. #trailrunning

First (and biggest) run of the holidays, 1281m of ascent. Up to Plan de l'Aiguille, along the Grande Balcony Nord to Montenvers, and back to the campsite. #trailrunning

A wee video of our trip last weekend, the views were glorious. Don't think I've ever had it hotter in the Scottish hills #hiking #wildcamping #munrobagging youtu.be/-dD0PLyf1oQ

Consistency pays off. Finally tipped over into the next category in my Garmin Endurance Score. Now to aim for "elite". #running

Our Saturday evening camping spot. ❤️🏴󠁧󠁢󠁳󠁣󠁴󠁿 #wildcamping #scotland

Anyone get a bit twitchy on recovery weeks when they see this? #running #runningtraining

A milestone week, first time in training I've hit an overall volume of 80km (1066m of ascent), mostly in back-to-back long runs. Now into a recovery week. #running #trailrunning www.youtube.com/watch?v=525w...

performance.now(), the web performance conference, 30th and 31st of October, Amsterdam. Single track, the best speakers in the industry, plenty of your performance-mad peers around to have fascinating conversations. What's not to like? Let's introduce our speakers ... perfnow.nl

Well, that was tough going! First ever marathon distance training run, longest run by 8km, biggest overall running week at 76km. It was 664m of ascent and some of the paths were so overgrown that the going was difficult. Last 10km were hard, had IT band pain on my right knee. #running #trailrunning

Ready for tomorrow's long run! #trailrunning #running

Biggest run so far, yesterday. 34km with 960m of ascent. It was tough going! On the West Highland Way, Bridge of Orchy to Kinlochleven. #trailrunning #trailrunner youtu.be/wbnDcBFGwlg

Trying to decide what to wear tomorrow, jacket and shorts, full waterproofs or a wetsuit. At least there isn't much wind forecast. #trailrunning

Not the best run ever, tight calves and shins for most of it, just didn't feel smooth. But still managed to do 95% in zone 2, so that's a tick. It'll be a 54km week by the time I've had a recovery run tomorrow. Still a long way to go before I'm a 50 mile runner! #trailrunning youtu.be/3-83tWyAgww

Recent focus has just been about building more base and it's nice to feel I can now run longer distances at lower effort. youtu.be/wivgPoEeFqs #trailrunning

Beautiful installation on the beach in our village today youtu.be/qIhbhsExlFM (bit windy for the drone) #publicart

Well, that was a fun weekend! Short run on Saturday to save my legs for Sunday's Kickboxing grading, pizza from our brick oven on Saturday evening (taking carb loading seriously) then mountain biking with a couple of dads and the kids. #running #kickboxing #pizzaoven #mtb

It's the most wonderful time of the year! Carb loading for tomorrow's kickboxing grading #pizza

While not technically a trail run apart from the last 5km, I had a great day out on Sunday with my daughter, did 7 mountains. #trailrunning #hiking youtu.be/PZ49nt4Xpfk

Slow but steady progress on my long runs. From Sunday's 32km: - 79% in Z2, vs. 65% 2 weeks ago - All but the last 6 km in Z2, vs. 12km in Z3 2 weeks ago - Relative effort 115, vs. 145 2 weeks ago - Pace 5:55/km, vs. 6:10/km 2 weeks ago #trailrunning #running youtu.be/KXQqUKPeaAs

If you eat out-of-date jalapenos you might get food poisoning and not being able to run for a few days. Follow me for more top running tips! youtu.be/2AClcK0n7g0 #running #trailrunning

We're back home and I'm already missing the Lake District. My long run on our first day left me with DOMS for the rest of the week and left me with memories for a lifetime. Truly my biggest and best run to-date. #trailrunning #running youtu.be/FlQ6zy6iumw

A break from #trailrunning today, beautiful day for some #wildswimming in upper Eskdale. We've had an amazing time in the Lake District, cloudless skies every day.

What an incredible week we're having in the lake district, a mixture of #trailrunning #hillwalking and #wildswimming Luck like this with the weather doesn't come along very often. youtube.com/shorts/PJvBM...

Epic 27km, 1600m ascent run this morning, starting in Eskdale, heading up Scafell, down scrambling and up to Scafell Pike. Over 5hrs on feet. Tired but nothing feels broken. The weather could not have been better. youtube.com/shorts/Cf7fu... #trailrunning #running

Saturday's #trailrunning plan. A lot of ascent (for me) and a lot of sunshine. It's going to be epic. I am *so* excited for this run. #running

Recently feeling quite fatigued in the legs, but I might have turned the corner! My last long run was 4 days ago, I've run the 3 days since, and while my legs are a bit tired, they're not sore! It's the first time I've ever run 4 days consecutively. #running youtube.com/shorts/sgivj...

Heavy legs for the first third, but managed to push through. Felt easier 2 weeks ago. Progress is not a linear process. Looking forward to seeing how it feels after a few weeks of doing this route. #trailrunning #running #runningtraining

Picking up a bunch of flours for mother's day...

A must watch film. We are in awe of our co-founder Jasmin. Just watching this film brings back the emotions of waiting for Keith’s tweet in 2024. The drive, tenacity and endurance 🤩 The wonderful trail running community also shines through 😍 #bm100 youtu.be/PgTEsybXw-4?...
