Tracker service plans are so expensive there's no point in bying one if you can rent from the organiser. I think the cheapest Spot Trace was 100€ and the basic service plan has to be bought for a year or more and that's something like 180€ with taxes.
Quick look at my Revolut shows £1491 during TCR.
That's just stuff spent in forrun so obviously doesn't include bike, kit, flights, race entry, tracker, insurance, etc.
