I'm a 44 yo male with over 40 400, 800, mile, 5k, and marathon performances of 59s, 2:10, 4:41 16:20, and 2:39.
If I had horrible luck I could conceivably be grouped with a 50 second 400 runner, a 1:55 800 runner, a 4:20 miler. a 15:00 5k runner and a sub 2:25 marathoner. With a 100m lead, I would get caught by either the miler or the 5k runner no matter how I paced my effort.
However ,there were about 2.8 million HS graduates per year in the mid 90s. That means there are about 1.4 million American males my age right now.
So a sample size of 1000 equals 1/1400 of the total 44 yo male population. That means, I've got even odds the best runners in my field are no better than the 700th overall runner in any one event. I'm not sure if thats the best way to analyze it statistically but go with that for the moment.
I'd guesstimate the 700th best times for 44 yo runners right now off the couch with no add'l training allowed as something like:
400-58
800-2:15
Mile- 5:20
5k - 18:00
Marathon 3:00
So with a 100 m headstart I would need to run a 75/75 800 to just barely stay in front of the 400/800 guys, then run 6:00 pace through 5k to stay ahead of the miler and the 5k runner and then average 6:55 miles to stay ahead of the marathoner.
I'd take that bet against a "typical" field.
I'd probably lose about 5% of the time against random draws with better runners if I had to run it blind without knowing my competitors' abilities. Give me do or die wavelight pacing based on the field's abilities and I think I could get my execution odds down to around 1%.
I am going to ignore the 24 hr part of the hypothetical because its really just asking if I could outrun a so-so middle aged ultramarathoner. The answer to that is nobody cares about ultras.
