Tracking macros can be a helpful tool — but for many (especially athletes or those with disordered eating histories), it can create the feeling of control while disconnecting you from your body.

Here’s why: ⠀ 🔸 It values numbers over intuition 🔸 It’s based on imperfect data (labels, apps, wearables = estimates) 🔸 It reinforces rigid thinking and guilt around food 🔸 It ignores how stress, sleep, hormones, and training affect your needs 🔸 It can mask disordered patterns as “discipline” ⠀ Eating well for your health and performance doesn’t come from perfect numbers. It comes from flexibility, awareness, and trust in your body.

✨ If control feels like safety, ask: Is this truly fueling me — or feeding my fear?

What should you do instead ?

⭐️Seek an Individualized, whole-food–based meal plan which will help create sustainable eating patterns tailored to your training demands and lifestyle—not chasing numbers

⭐️Focus on food quality, fueling timing, recovery, and mindset: Prioritizing performance and wellbeing over rigid tracking.

⭐️Periodic check-in vs daily logging: For many athletes, regular reflection and adjustments trump obsessive daily tracking.

Creatine is on the lips of everyone at the moment. One of the most researched & effective supplements around to aid performance .
We know the benefits for strength focused athletes but what about for Endurance Athletes ?
The message is not so clear cut ….

💥 What It Does?
Creatine increases phosphocreatine in muscles, boosting short bursts of high-intensity effort—helpful for sprints, hills, or strong finishes.

🏃🏼Enhanced High-Intensity Performance:
Creatine can improve short bursts of high-intensity effort—like sprinting, hill climbs, or surges in a race—common in endurance sports.

💪Improved Training Capacity:
By boosting phosphocreatine stores, athletes may be able to train harder and recover faster between intervals or strength sessions

🥯Increased Muscle Glycogen Storage:
Creatine may help store more glycogen in muscles, which is crucial for endurance performance, especially in long events.

🧠Neuroprotective & Cellular Benefits:
Emerging research suggests creatine could support brain function and reduce oxidative stress—both important during prolonged exertion.

📖In summary creatine helps endurance athletes most when the sport includes short, powerful efforts—or during training phases focused on strength, speed, or recovery. It’s less helpful for long, steady-state events.

”The only way to make sense out of change is to plunge into it, move with it, and join the dance.”
There has been lots of change for me this year which at times has been unsettling but feel there is more to come.
I said I wasn’t interested in competing…..how many of you knew I was lying? 🤣

Manchester Marathon is here again. I have so many athletes running this ever growing race this year !
Marathons are a strange form of enjoyment ……for me the enjoyment was only at the end 🤣 . Also a bit like child birth ….you are horrified by the pain but then you forget and go back for more.
Good luck to all of you .

📷 to remind myself that once upon a time I could actually run quite well 🌟🤣

I was flicking though the book “The boy, the mole, the fox and the horse “ the other day and this page made
me smile at its perfect accuracy.
You can be held in a state of restrictive eating due to poor body image and negative perception of self . You may feel “ if I look thinner“ or “ leaner ” I will feel happier or look more like a runner .
In this process of restriction to achieve weight loss , you forget about what’s going on inside your body . You forget about how hard your body works for you 24/7….an incredible factory of intricate processes going on behind the scenes to enable you to do what you want when you want .
In this drive for external perfection you run the risk of damaging what’s most important - your internal wellbeing and health .
Nothing is truer than remembering
.
“We can only see the outside but nearly everything that happens is on the inside”
