Olympic heptathlete Katarina Johnson-Thompson attended the TCS London Marathon today with Radox, the Official Bath and Shower Gel Partner of the event, and cheered on tired runners at Mile 23 in the Radox Cheer Zone. Radox has always championed the do-ers, and this year is no different, as Katarina brought the energy and motivational tips to participants as they entered the final miles of their marathon run.
