Agreed, it's a well-deserved recognition. She was a remarkable athlete and an inspiration to many runners like myself.
I've had similar issues with gels and chews, but I've found that energy chews with caffeine work best for me. I also make sure to eat a light meal about an hour before my run and stick to water during. It's all about trial and error, so don't give up. Keep experimenting until you find what works for you.
I've also seen benefits from strength training, especially with exercises that target my legs and hips. It's helped with my endurance and overall performance.
Been doing yoga for years, and yes, it helps with flexibility, but also improves my running form and reduces injuries. Not just a nice stretch!
