Tough day at the office today for #TheBigHalf in London with the #OnePercentRunningClub crew…but I escaped with my life! 😅💪🏾

Another half marathon, this time #TheBigHalf taking in some of the London Marathon course & some famous landmarks. Not pleased with the time tbh, heat & prep not ideal but great experience ahead of a winter's worth of training. Oh, and I got the boat home

F*** that was a hot one!! 🥵🏃🏻‍♀️A really tough run at #theBigHalf but not a bad time of 1:47:09 given the heat... #halfmarathon #running #WeRunAsOne #ukrunchat

Lets make some noise London!! 🤩 At the start line for #TheBigHalf - great atmosphere as usual. Ignore the madness in the world - this is what humanity is about! #HalfMarathon #running #ukrunchat #werunasone #BigHalf2025

Good luck to our biggest ever teams in the #GreatNorthRun in #Newcastle and #TheBigHalf in #London today! 🥇
