Not my day, but grateful I found a way to the finish line of marathon #3 after 7 years away! ☺️

I lost over 8 minutes in the bathrooms today and probably will have to get another colonoscopy despite having a clear one in June... 😩 What happened today was similar (but worse) to what happened in September on a 20 miler. But after numerous GI appointments/tests without a clear reason for my issues + an improvement, I was cleared by my GI to return to easy running + run a 16 miler a few weeks ago. That one went well without issues, so my GI doctor cleared me to still run the marathon today, but to be very cautious.

I knew after missing my peak week that I had to table my initial sub 3 goal. I decided to target a more realistic 3:10-3:15 instead. My legs felt fantastic all race and I held back on the pace the first half, then tried to negative split since I felt so good, but around mile 10 my GI started to feel like it did in Sept. and by mile 21 I had to make a long stop and other short ones…. 😣 I called .laurarun after 21 and said I should probably drop out due to GI issues, but I don’t want to as I’m so close to finishing. She suggested I jog it in versus dropping out if I felt I could. We figured I could still go sub 3:25, which is all I need for a 2027 qualifier.

Idk if it was smart, but I was determined to finish. 😭 I felt scared after mile 21, so I texted multiple people including my mom as I tried to carry on. My mom then called me and talked to me on the phone from ~mile 22-the finish and it was everything today! 🥹

Also, a special shoutout to for the race entry, Matt for being my running buddy the first ~12 miles, Carolyn + my athlete Adam for their PRs in tough conditions, my SIL and husband for somehow both still going under 3 hours, Emily + Grace on their 1st marathons, and all my family/ friends/ clients who ran today or cheered me in person or afar. 🫶🏻

I’m not sure what my running future holds as I still have to get my seemingly 20 miler and above induced GI issues figured out. 🙃 But I know I am capable of sub 3 when I’m healthy and can string together a full training cycle. The dream continues!

After 7 long years… marathon number 3 is loading! And of course it’s the only marathon I’ve run, my favorite Bank of America Chicago Marathon!😍 A special thanks to Runner's World for the entry! ☺️

We don’t have to do this, we GET to do this. After all I’ve been through in health and life since my last marathon in 2019, I’m so grateful to have made it to this start line! 🥹 Shoutout to Laura Filla for coaching me to this point the last 3 years! 🥰 Running a race is a privilege I’ll never take for granted! 🫶🏻 We cannot control the weather, but we can control our attitude, our hydration, and our fueling for tomorrow.

With an unexpected health issue that cropped up late this training cycle and required some training adjustments, my goal for the race has changed. I’m thankfully feeling better the last couple weeks. Despite the adjustments, I’m still excited to get out there, do my best on the day, and most importantly have fun! 🤩

I hope to see so many of you out there running or cheering tomorrow! 🎉

Who’s carb loading this week for the or soon for a different half or full marathon?! 🙋🏼‍♀️

If you’re vegan, there are a few additional carb load considerations, but hopefully this post is helpful!

And if you’re struggling to plan your carb load for an upcoming race as a runner (vegan or not) feel free to reach out for more personalized guidance! DM me, fill out the interest form in my bio, or email [email protected]. Although, as a heads up, I’m currently booked pretty far out, so act soon if you have an early 2027 race!

I’m in network with many Blue Cross Blue Shield and United Healthcare insurance plans + I have self-pay options if you have a different insurance or your insurance doesn’t cover dietitian visits. Most of my insurance clients have paid $0 out of pocket to work with me, which has been amazing! 🤩

You do not have to wing it for your carb load or fueling your races in general. I’m happy to help and you do not need to be vegan-I work with all types of eaters! ☺️

If this post was helpful feel free to share in your stories or with friends! What is your favorite food(s) for the carb load?! Share below to help others with ideas. ⬇️ I shared some of mine in this post! ⬆️ Also, isn’t this audio hilarious?! 🤣

Amanda Wagner Nutrition is officially 3 years old! 🥳 Well technically we are 3 years + 3 days old as my business anniversary was September 8th, but I was so busy I forgot to celebrate! 🙈

If you’re reading this post right now it means you are a current/former/future client, a friend, a family member, a colleague, a fellow runner or athlete, a plant-based person, or a general fan of me + my business. And for that I want to thank you greatly! 🫶🏻

Thanks for trusting me enough to learn about nutrition from me (whether plant-based, sports nutrition, REDs, or general), to learn about running/fitness from me, and/or to support the work I am doing as a one woman show! Every share of my website and/or social media posts, review or testimonial written, referral to Amanda Wagner Nutrition, and even smaller things like words of encouragement help me more than you all know! 🥰

I have learned so much and I am so proud of how AWN has grown in 3 short years. 🤯

My proudest accomplishments of year 3: significantly increasing my annual income (no easy feat in the current landscape, but it aligns with my values to continue accepting insurances despite the ups/downs), getting quoted in and as both are personally meaningful to me + a few other publications, getting a new office which allows me to conduct in-person sessions (although most prefer virtual), and several speaking opportunities from running teams to an upcoming plant-based athlete presentation on carbs through ! I would not be here if it was not for the support of all of you! 🫶🏻

And after a VERY busy 2026 so far I am excited to share I finally have one opening for a new client in mid October! 💃I’m in network with most BCBS and UHC insurances! And many people who use insurance find that their dietitian visits are fully covered! 🙌🏻 I also offer payment plans or take HSA cards for clients. Inquire via the contact form in my bio or email me. 🔗

I’m dreaming big for year 4 of business! 🤩 For my fellow private practice/biz owners, what’s one thing you are proud of or learned in your first few years?! 👇🏻

If there isn’t dessert I don’t want to go. 🙂‍↔️

Here’s your sports dietitian and running coach reminder that whether it’s after a long run/ ride/ swim or on a rest day, you can have dessert. 🫶🏻

Running at different levels over the years has taught me that nutrition isn’t about being “perfect.” It’s about consistently fueling your body, supporting your performance, and enjoying your life along the way. ☺️

Long runs, rides, swims, and hard workouts require plenty of fuel, but don’t forget that rest days are when your body repairs, adapts, and gets stronger. 💪🏻 Recovery is work, too! And neither type of day calls for guilt around food.

A sustainable approach to nutrition makes room for all foods, including dessert, because building a strong body, fueling for performance, and a healthy relationship with food all go hand in hand! 😋🍨🧁

Runners 🤝 Carbs

And many runners are surprised to learn that if carbohydrate intake is too low, the body doesn’t simply stop needing them. Instead, it creates glucose through a process called gluconeogenesis.

In the simplest terms, think of gluconeogenesis as your body’s backup plan.

When it doesn’t get enough carbohydrates from food, it starts making glucose from other sources, including amino acids from protein.

Meaning, sources normally used in recovery and rebuilding, get recruited elsewhere.

Why does that matter?

That’s why adequate carbohydrate intake is so important for runners looking to perform and recover well. And being able to leverage that might be one of the most powerful tools you have in your training.

In our recent Laces and Legends conversation, Amanda Wagner breaks down why carbohydrates are often misunderstood and why eating enough can actually support both performance and body composition goals.

This is a topic we discuss frequently with athletes at Filla Endurance.

The goal isn’t simply to train hard. It’s to give your body the fuel it needs to adapt to that training so training actually works.

Amanda is a Registered Dietitian, run coach, and member of the Filla Endurance coaching team. Her expertise helps athletes bridge the gap between training and nutrition so they can perform at their best.

What if the reason you’re struggling through summer runs isn’t your fitness or even the heat?

In our latest Laces & Legends episode, registered dietitian and UESCA certified run coach Amanda Wagner joins us to discuss one of the most overlooked performance factors for runners: fueling and hydration.

We talk about:

• Common hydration mistakes runners make in the heat

• Why carbs matter more than many runners realize

• Signs you may be underfueling (including one side effect that might surprise you)

• How proper fueling supports performance, recovery, bone health, and long-term well-being

• Practical strategies you can start using on your next run
