This is all the most useful data I have. I wrote and journaled my attempt and experience on Polarsteps, so my family knew what was up. I also carried a Garmin Inreach 2, and have its tracking data if needed. However, I didn't add it since it's identical to my Garmin Fenix 6 Pro data. All my pictures are very large in size and I have many, many of them. Here is the link to my bucket again, [https://Kaya-Sem.quickconnect.to/mo/sharing/tzqPaNiHa]. These are the originals with all the metadata. Note that there are pictures from before the start, and from after I finished. A more curated collection is on Polarsteps, but those have no metadata. Also, there is an extra day in Polarsteps for the day I stayed in Meghri before I started hiking.
There is an official TCT hiking slack, in which the organisers posts updates and where hikers chat and share information. There are a couple of people who can vouch for me and my attempt. I can share information if needed. Please submit an email for that with contact information.
It's split up day by day, and I wrote about the day in the evening.
