I do quite a lot of work with various races (on-course medical) pre-covid, and would be happy to share with you (or anyone) what I deem to be essential carry items from a medical perspective. However, it would seem to me, based on your comments, you've got a decent handle on it.
More importantly, these articles have been a refreshing change from the usual mtb content. Rider perspectives, especially in the areas or race and representation, help all of us become more aware of the struggles our brothers and sisters face daily - and hopefully we can lend our voices/actions to making everyone feel more included.
We all have a part to play - lets continue to strive for more inclusion.
