I have been looking at how to factor age and weight when comparing rowing times. The following link is for 2000m, but I mainly row 5000m, so I will linearly extrapolate (not 100% accurate but acceptable).

Two example rowers are shown below

• If Person 2 were to be rowing at the same level as Person 1, what time would he need to do to be on a par with Person 1:

17m 58s  = 1078 seconds

Weight adjustment: 1.059/0.979 = 1.082*1078 = 1167 seconds = 19m 27 seconds

Age adjustment: 1.6seconds *(5000/2000) = 4 seconds.

So person 2 would have to complete 5000m in approximately 19m 31 seconds to be on par with Person 1

• Alternatively, assuming Person 2 were to travel on a very fast spaceship and therefore didn't age compared to those on Earth, how old would Person 1 be before he slowed down to Person 2's speed.

22m 08s - 17m 58s = 250 seconds

~ 100 seconds over 2000m

Person 1 would have to be around 73 years of age before Person 2 can land his spacecraft and win!!
