as for the outfit change, let me know what you think. maybe they were breakaway windsuit pants like the kind commonly worn in the 1990s?
No, those look like regular running pants, which even with a zipper at the bottom can sometimes be hard to take off over running shoes.
And one doesn't just toss away nice running clothes like this, so where did they go?
Mostly, however, no serious sub 3-hour marathoner is going to stop by remove their clothes and start running again.
It looks like he wants to appear as 'Joe-slow' at the beginning so there is less suspicion if he fades off the course, and then wants to appear more as a serious runner when he reappears back on the course.
Also note that in none of the finish line pictures which have been linked does he even looks like he has broken a sweat or pushed himself across the line to get a fast time.
