RED-S and Low Energy Availability: the commonly overlooked syndrome in sport.

April 6, 2026 by aletheam Leave a Comment

If you train regularly, eat “well,” and still feel like your body isn’t responding the way it should, this is something that should be on your radar. Relative Energy Deficiency in Sport (RED-S) is a common thing I see in clinic and even though it’s more well known now than years ago, most people aren’t sure how to assess if it’s something that is affecting them. It can be tricky as it’s not extreme, not always intentional and it can affect the weekend warrior just as easily as it can affect an elite athlete. What is RED-S? RED-S occurs when the body doesn’t have enough energy available to support both exercise and normal physiological function. It was once known as the Female Athlete Triad, which focused on: We now know ...

Tart Cherry Juice: A Natural Support for Sleep, Recovery, and Inflammation If you’ve ever found yourself tossing and turning at night or waking up feeling sore and tired after training, tart cherry juice could be for you.

Maximise Your Race: The DIY Sweat Test for Athletes

August 5, 2023 by aletheam Leave a Comment

Nailing your nutrition and staying hydrated is like rocket fuel for your performance. However, we are all very different when it comes to hydration, genetics, build and ethnicity all have different sweat rates. That's why the sweat test is your secret weapon to fine-tune your race day nutrition plan. I'm here to show you how to do your own sweat test so you can rock your runs and rides. Firstly, you want to do the test on a day with the same temperature and humidity to your race day, this will give you the best results & accuracy for race day. Let's Go! This is what you need to do: Now for the maths to calculate your sweat rate: Sweat Rate (L/hr) = (Pre-workout weight - Post-workout weight + Fluid Intake) / Workout ...

Be a Marathon Rockstar: Fuel Your Success from Start to Finish

June 12, 2023 by aletheam Leave a Comment

I work with a range of running levels from novice to the well-seasoned ultra-athlete. This blog has information for all runners; however, it is intended for the newer marathon runners. I ran my first half marathon with no knowledge of running, nutrition or recovery. I went in 100%, I trained at 100%, every run was at effort, I thought if I ran every run as fast as I could, I would naturally start to run faster, wow, was I wrong! I was under fuelling, not intentionally, I truly believed I was eating well at the time. I trained with an old school phone (way before owning a Garmin) that shouted out when I had hit another “k” that I for some strange reason decided to not take to the event. This all led to a bucket load of excitement at the ...

Simple (but important) Things to Know about Electrolytes

February 9, 2020 by aletheam 1 Comment

Are you one of those athletes with rings of white on your hat post-training? Are you feeling fatigued at the end of a session? Are you feeling smashed for the day post-training sessions? Are you training in your luteal phase? Answered yes to any of these? You may need to consider an electrolyte replacement. What are Electrolytes? Electrolytes are salts that are found in nature in the form of minerals. They have an electrical charge, either a positive or a negative ion, that is part of our nerve communication system. They speak to the opposite ion; the negative will communicate with the positive i.e. opposites attract! I mean do opposites really attract? I don’t know about that but in this case, they do! In addition ...

Half marathon road trip extravaganza ✨ We ate, Half marathon road trip extravaganza ✨ 
We ate, drank, ran, recovered, drove and discovered a beautiful pocket of Victoria.

Stop over in Geelong with dinner at Nectar. A stop off at for lunch at Morta Deli in Torquay then on to Wye River with incredible accommodation overlooking Great Ocean Road (thanks Anita 🤍). Food here was all about the half marathon before and after (will do a post on that for the few people who asked). 

Great Ocean Road run was awesome, I really loved it! It was Ben’s first ever half and he smashed it 💥 

Next stop Port Fairy and we all loved it! An unexpected delicious fresh meal at a pub, restaurant was called The Stump.

Then off to Daylesford, I’ve been there before and still love it 😍 We did a sauna and bath hour to help the tired muscles but mostly ate 😉 Highly recommend Bar Merenda, Bistro Terroir and the anchovy toast and wine at Winespeake 🙌🏼 Delicious pastries and coffee at Wombat Hill Cafe. Thanks for all the Daylesford tips @joyously.aware 🙏🏼

Big thanks to @richardsnowdenrealestate who held down the house, dog and reno while I was away, we missed you ❣️
23km of the Great Ocean Road done 🌊🏃🏼‍♀️

I like having goals. I actually love having something to work towards and the structure of training. I like having a reason to train. 

The legs felt good today. Even with those hills I beat my Queenstown half time 😅 Huge thanks to @coach_kissick @whynot_performance_ for building my strength and @run_coaching for guiding us through!

Went from gale force winds and pouring rain before the start, then clearing to just a few showers and actually ending up being a cracker day!

Pre-race fuel looked like:
🥣 ~20g Coco Pops
🥤 1/3 bottle Rokeby Chocolate
🍯 Crumpet with honey

Race fuel:
⚡️ Clif Bloks Salted Margarita every 30 mins
⚡️ Swapped to Precision Fuel later on

Only around 30g carbs/hour for me today, which is lower than I’d normally aim for, but my gut still hasn’t fully recovered after antibiotics so this felt like my happy place to keep energy stable without upsetting my stomach.

Post-race was:
🥤 The rest of the Rokeby
🥔 Chips (the salt tasted AMAZING)
🍔 Chicken burger for lunch
🥗 Leftover roast chicken, veggies, fresh salad and a mandarin for dinner.

A good reminder that sports nutrition doesn’t need to be “perfect” nutrition.

👇🏼What’s your go-to race fuel and favourite post-race food?
Absolute legend 🙌🏼 Run like a girl they say Absolute legend 🙌🏼 Run like a girl they say 🤔
Hallelujah ✨ Hallelujah ✨
