Too many emotions to put into words! This one is for my team who have supported me no matter what, but especially my coach @danlorang who never gave up on me after all these years! 📸 @jamesmitchell5 / @ironmantrispain #IMVitoriaGasteiz #AFightingChance

My new swimming routine. Since the beginning of the year, I’ve been working on my swimming technique with @nickastelein The process we’ve put in place has really helped me take a step forward: understanding my flaws, building targeted drills to correct them, and most importantly, using video to see what’s holding me back. We also use eo SwimBETTER sensors by @eosportslab , which allow us to analyze my stroke more precisely, measure my efficiency in the water, and track its evolution over time. Today, I’m able to swim in a more efficient, relaxed and economical way. 📸 @unloop.prod - @quentin.lblc

Taking any opportunity to rest the pins after another solid week with the @aslturismoesportivo crew! Girona speaks for itself. New friendships, old training routes and a lot of suffering. 📸 @guillemraphotosports

Running through the city while everyone still sleeps has to be one of life’s greatest pleasures right?! Finishing just as the coffee shops open? Even better.

Kyoto marathon in 2:34 on a bumpy but fun course. My takeaways from this last week: ▪️marathon running is still tough! ▪️Kyoto is an amazing place to train ▪️my favourite way to explore a city is to swim, ride and run through it ▪️the coffee is world class I’ve still got a couple of weeks left but already looking forward to the Kyoto edition of our NKC Training Camps in September! Thanks to the @overlandrunningprovisions community for the extra weekly motivation 🤜🏻🤛🏻
