I&#39;m hoping it&#39;s just restless sleep from bashed up legs and an unfamiliar bed.<br/><br/>I do often get a one-night drop like this after a heavy effort like a race, but perceived exertion wasnt that high over the week. Total load was about 20 hours on feet though, which is more than double my baseline (6-8 hrs/week). So could be accumulated fatigue.<br/><br/>#Garmin #running<br/> <img src="https://media.mathstodon.xyz/media_attachments/files/114/372/248/513/183/641/original/baf60d6514921bd9.jpg"> <br/> 2025-04-20T20:53:39Z https://yabu.me/nevent1qqs8mzscqlpx3s8faap2xdqhr7dxpu8l3wj5nx277ydej2qrv5ds4wgzyrl5jv57g8z3y5ecjs8aruk3azaewlr5fgcww4y0qdq7rqdk6twax9ant32 That&#39;s a wrap on a busy training week in Eryri. One (1) day of good weather and 5 of wind and rain. I trained 4 days out of 6, with 2 rest days (enforced by the weather, but probably a good idea.)<br/><br/>I seconded some grade 2 and 3 scrambles in the Glyderau as part of a course. It was my first time at this grade and made trickier due to weather conditions and greasy rock. (Routes completed: Idwal Buttress on Glyder Fawr, Chimney Crack on Tryfan Bach, Bastow Buttress Variant and North Tower on Tryfan, plus some grade 1 gullies in descent). <br/><br/>Challenging but highly enjoyable. I also solo ran/hiked/scrambled the Snowdon Horseshoe route, my first time up Crib Goch. <br/><br/>I&#39;d wanted to do two more classic horseshoes (Cwm Bochlywd, Carneddau Southern Ridges), but strong winds and heavy rain looked like too much risk. So I swapped in a low level run around the Ogwen Valley to get some elevation in on rough mountain terrain, with a bit of grade 1 scrambling up False Gribin too. <br/><br/>#TrailRunning #running #mountains #climbing #Wales #Cymru<br/> <img src="https://media.mathstodon.xyz/media_attachments/files/114/365/031/521/773/503/original/ade861683df7f0fa.jpg"> <br/> <img src="https://media.mathstodon.xyz/media_attachments/files/114/365/031/549/010/291/original/708934e6ec9249cb.jpg"> <br/> <img src="https://media.mathstodon.xyz/media_attachments/files/114/365/031/474/456/868/original/f000871039bf9835.jpg"> <br/> <img src="https://media.mathstodon.xyz/media_attachments/files/114/365/031/472/829/442/original/850f89974273078e.jpg"> <br/> 2025-04-19T14:31:20Z https://yabu.me/nevent1qqspj654aysnallfa06aqtk7mrxs5tuaw2tazck2rnrlu79nergzz4czyrl5jv57g8z3y5ecjs8aruk3azaewlr5fgcww4y0qdq7rqdk6twaxcssc9d In reply to <a href='/nevent1qqsf5qwc9jp7mfk028zt88napqqqwv5834m0uecrwdka9n9dj0fxlhsk4tfhk'>nevent1q…tfhk</a><br/>_________________________<br/><br/>Garmin Connect -&gt; More -&gt; Garmin Devices -&gt; [Your Watch] -&gt; User Profile -&gt; Heart Rate &amp; Power Zones<br/><br/>Yup, buried deep in the menus! 2025-04-19T06:22:02Z https://yabu.me/nevent1qqs2q6paatzay5shlx95kcegrezttewdmcvk2heau8p22fp7dr5hq5qzyrl5jv57g8z3y5ecjs8aruk3azaewlr5fgcww4y0qdq7rqdk6twaxvsgm8y Managed to sprain my ankle... in the gym 🫤<br/><br/>Standard medical advice is RICE or variants of it (Rest Ice Compression Elevation). But last time I followed this I ended up with my calf wasting away and a weakened ankle for months. Reading around it, it seems like the advice is weakly evidenced, and light activity using pain as a signal to desist may lead to a quicker recovery: <a href="https://marathonhandbook.com/rice/">https://marathonhandbook.com/rice/</a><br/><br/>#running 2025-02-10T20:50:49Z https://yabu.me/nevent1qqs2yre4hpx4hlew72glnet39taqt8av7yc6xecmylss8pk3270wvqszyrl5jv57g8z3y5ecjs8aruk3azaewlr5fgcww4y0qdq7rqdk6twaxckefa2 The Arc 25 mandatory kit logistics is harder work than the race 😂<br/><br/>I had to upgrade to a 20L pack from my usual 10L, but it does all pack down (just). Weighs a lot though. I have been training with a loaded pack and it&#39;s enough to induce walking on some inclines. <br/><br/>2 separate headtorches each with dedicated backup power feels like overkill for what&#39;s probably 2 or 3 hours of night running tops. I&#39;m guessing they copy/pasted the kit from Arc 100 and didn&#39;t prune as much as they could. <br/><br/>Not pictured: compass (for a coastal path?!). <br/><br/>#running<br/> <img src="https://media.mathstodon.xyz/media_attachments/files/113/856/110/383/863/537/original/0360d3048fca2e02.jpg"> <br/> <img src="https://media.mathstodon.xyz/media_attachments/files/113/856/110/568/455/551/original/f42cfb98a4c81990.jpg"> <br/> 2025-01-19T17:10:01Z https://yabu.me/nevent1qqs078ztwak7p5g729ekusntnrv08mx6mg5xqllssx3v3dv47evqqzqzyrl5jv57g8z3y5ecjs8aruk3azaewlr5fgcww4y0qdq7rqdk6twaxwr9tmv In reply to <a href='/nevent1qqsv8p3cyhw9fvnaw8vygjwtsezgnzru6jxsmvflz2xq82un32xm0ngya3j4y'>nevent1q…3j4y</a><br/>_________________________<br/><br/>The potholes use-case is so sympomatic of magical thinking technosolutionism. The idea is to feed a network of cameras covering the roads into training a pothole detecting algorithm.<br/><br/>But the reason there&#39;s so many potholes isn&#39;t because authorities don&#39;t detect them, it&#39;s because they&#39;re starved of resources (in some cases actually bankrupt) and are having to prioritise statutory services like social care. So even if there&#39;s enough camera coverage for this to &#34;work&#34; it&#39;s pointless unless there&#39;s actually a budget for maintenance crews. <br/><br/>Even if you want a tech solution here, predictive maintenance using traffic levels, local weather, and stats/ML would likely have more value. But that&#39;s not &#34;AI&#34; it&#39;s just sparkling operations research so it doesn&#39;t get considered anyway. 2025-01-13T08:53:18Z https://yabu.me/nevent1qqsv8p3cyhw9fvnaw8vygjwtsezgnzru6jxsmvflz2xq82un32xm0ngzyrl5jv57g8z3y5ecjs8aruk3azaewlr5fgcww4y0qdq7rqdk6twax9qvmsf Did an LLM write this policy?

And then you can start this game of back-and-forth. Can you articulate your gut instinct and place it within a rational discussion? If there’s still a disconnect, can you visualize why? As you play that game, your imagination will gradually reconfigure. And in the end, if you’re persistent, your instinct and your reason will align, and you will be smarter.
