If me and Abhishek dada have a running race, who do you think would win in your opinion?

In my school days I was pretty slow and used to lose against other boys even juniors. But in my opinion I should win most likely. Thats because I am 20 and he is 27-28 yr old. I feel a 20 yr old is more faster and energetic than a guy in his late 20s. Also he is quite fat so he would be slow too but again in schoo days i lost against fatter boys in races too. Who do you think would win?
