To make a long story short, I participated in the T100 Sprint. It was my first triathlon, and I flew in from another country.. incredibly excited. Until I finished and wanted to check my results. NO. FINISH. TIME. Apparently, I didn't finish the run. How the fuck is that even possible when I literally crossed the finish line? My Garmin proves I did... I finished the sprint and even received a medal. Of course, it's not the end of the world. I got my medal and I know I finished. But still... T100 is telling me to contact Sportstats, which is honestly weird. I'm pretty sure if the "fast" participants had been affected, this would've been sorted out ASAP instead of sending everyone the same copy paste email telling us to contact Sportstats ourselves. Sportstats is of course not replying to the emails sent by participants that were affecteed. And it's not like this only happened to a handful of people. There are literally more than 15 pages (https://sportstats.one/event/t100-triathlon-world-tour-london-uk/leaderboard/145707) of participants without finish times if you look at the results. This isn't an isolated issue which means T100 should take responsibility instead of passing the problem on. It's a shame, because the event itself was actually fun. Would I recommend it? Big fat NO.

Good event but there were a couple of logistical hiccups that could be fine-tuned for future races.
