Kiprotich gupta win lagos marathon
I think there may be a mistake here!
Kiprotich is a common Kenyan surname, and Eliud Kipchoge is a famous Kenyan long-distance runner who has won numerous marathons, including the Berlin Marathon and the London Marathon. However, I couldn't find any information on a person named Kiprotich Gupta winning the Lagos Marathon.
Gupta is a common Indian surname, and it's unlikely that someone with this surname would win a marathon in Lagos, Nigeria.
If you meant to ask about a different person or event, please feel free to clarify!
