Competitor bio:

Greg is a veteran of the 2025 World Marathon Challenge. After completing seven marathons on seven continents in six days — with very little sleep and plenty of moments questioning his own sanity — he came to a clear conclusion: yes, he should absolutely do this again. So here he is in 2026 — older, not necessarily smarter, and fully aware of what lies ahead — returning to the challenge once more. This time, Greg is running to raise money for KultureCity and its mission to make public spaces and events more accessible for individuals with sensory sensitivities and invisible disabilities. Seven marathons. Seven continents. Seven days. Two questionable decisions. One great cause. https://www.kulturecity.org/kc-fundraiser/greg-yaghmai-world-marathon-challenge-2026/
