It is the responsibility of the participant to monitor their own individual health.
Why are courses marked in miles instead of kilometers? Aside from marathons and halfs, many race distances are promoted in kilometers (5-K, 10-K, 15-K, et cetera). I train, as most runners do, on a 400-meter track, and all my training is done in kilometers. What’s with the hang-up on English measurements?
There's a marathon/half-marathon that I've been participating in for the last five years. Organizers used to allow a family member or friend to pick up a runner’s packet as long as they had a copy of the runner’s driver's license and a signed note from the runner. Since then, they have only allowed runners to pick up their own packets.
I just ran the Marine Corps Marathon, and my results only showed up online through 30K — something obviously went wrong with the timing system, and I am trying to sort it out. Does this technology always work? How often is it used? This was the first race for me where the timing system was on my bib.
