I made it 546 kilometres in 19 days, with ~350 left to go. Idk if my water filter failed or there was a hygiene slipup, but I woke up Thursday feeling super fatigued and that quickly slipped into beaver fever symptoms (or some kind of infection/parasite).
Now I've spent the last few days recovering on the couch and picking up reading again. Still feels like a big achievement, but I had a bit of a short time window to finish the trail. Now I'll probably be too busy for the rest of the warmer season and have to wait until next year. 
Sucks, but also still an absolutely amazing achievement. As a hiker those numbers are huge huge daily milage for such a long time. And to think it was one small mistake or an equipment malfunction that stopped you rather than your body or spirit giving up speaks volumes. I hope you get another crack at it next year.
I probably planned it a bit too ambitious in retrospect. I'm a very experienced adventurer and camper with some long canoe and cycling trips under my belt, so I'm well used to keeping up spirit and mental resilience in tough conditions, but never done a hike longer than a few days.
Hopefully you learned some lessons then for next time!
