I just saw a video clip linked to the front page. And my answer is that I would not help him under the circumstances. By the time Shelley passed by, Hawkins was already attended by at least two race officials. If they needed my help, they would let me know, otherwise I would let the officials handle this.
I was in a somewhat similar circumstance two years ago. I was having a race of my life until mile 24. Then I lost my coordination, and struggled through the last 2.2 miles. I fell down 3-4 times in the last half mile. Two people who had already finished their races passed by and said to each other "we cannot help him because he could get DQ'ed." (I was very thankful that they didn't.) When I fell for the last time with 50m to go, one of the volunteers try to help me get up. I yelled "don't touch me" to scare her off. I might not have been DQ'ed anyway, but it would have ruined my experience. (I ended up with a 2min+ PB in spite of multiple falls.) That's just me. Unless my long term health is seriously threatened, I would rather crawl to the finish line than getting help.
My week.
M: off.
T: 7 miles.
W: 11 miles.
R: 7 miles.
F: 7 miles.
SA: 7 miles.
SU: 16.7 miles. (last 5 miles @ 7:54-7:51-7:51-7:47-7:32)
The last 5 miles of my long run felt much easier than a week before, and I was actually able to get into the next gear in the final mile. Only two weeks to go to my marathon, and I am just a tiny bit more optimistic than a year ago.
Re swimming. I was swimming almost every week in 2016 and 2017. I have swam only once this year. What changed is the fitness tracker than I am wearing for my reward program. We are paid by our insurance company $1 each for (1) at least 500 steps within 7 minutes, six times a day, (2) at least 3000 steps in 30 minute, and (3) at least total 10,000 steps for the day. One problem is that the tracker does not work in water. So I have to take it off while I am swimming. Even if it worked in the water, 100 strokes per minute is not a realistic goal in the water. So instead of swimming for 30 minutes on my "rest" day, I am talking a 25-30 minutes walk to cover those 3,000 steps. Currently I don't have the time to do both, although I am hoping to change this in the fall. (I should have no problem with time constraint during summer.)
