🏅 Huge congratulations to Sophie on completing her FIRST EVER marathon! 🏃‍♀️

On Saturday 24th October, Sophie took on the Battersea Park Marathon and crossed the finish line in an incredible 4 hours 52 minutes. 26.2 miles, months of hard work, and one massive milestone ticked off. 👏

Behind every big race is a lot of preparation, and fuelling is a huge part of that. Sophie worked with our in-house nutrition pro Daz through Optimus Nutrition Support to make sure she was eating right throughout her training and properly fuelled on race day, so she had the energy to go the full distance. 🍌⚡

If you’ve got a goal of your own coming up, whether it’s your first 5K, a Hyrox, or a full marathon, Optimus Nutrition Support can help you get there. Speak to the team at reception to find out more.

Congratulations, Sophie. It’s a brilliant achievement, and everyone at Optimus is really proud of you! 💙

MEMBER WIN 🏆

Huge shoutout to Kieran, who has lost the equivalent of 15 litres of olive oil in weight through Optimus Nutrition Support! 🫒💪

As a chef, Kieran is surrounded by food 24/7 and spends his days cooking for other people, so sticking to a routine with his own eating is no easy task. That makes this progress even more impressive.

Kieran, you’re doing really well. You’ve come so far, and we’re looking forward to seeing how much further we can go together! 👏

If this sounds like something that could help you, get in touch with the team today. Nutrition Support starts from just £15 a month. 📩
