There are lots of things to consider when you choose a race: the date; the location; the distance; the price; the medal; the reputation of the organiser; race reports; the size; the surface; the aid stations; and the profile.
For longer races, you also need to consider the mandatory kit list. It’s part and parcel of the package, and any race director worth their salt will have details on their website, so you know what’s expected *before* signing up.
If you’re a runner who likes to run your ultras in a pair of shorts sipping dew from blades of grass and eating berries you garner along the way, I suggest finding races with minimal kit lists. Do not sign up for races with comprehensive lists and then (a) moan about the need for a large pack or (b) leave half the kit in your car once you’ve passed the mandatory kit check.
Whether or not you agree with the necessity of every item is immaterial. Whether or not you choose to engage the race director in a discussion about the merits of a back up light source is up to you. But you chose the race and that means agreeing to be bound by its rules.
