A couple of years ago. I posted in a running group for advice on Facebook. Within an hour JS had messaged me, promising the world. It was around this time I googled him and thank goodness a LRC thread came up about "Emma" who turned out to be a high school or college kid, running the times js claimed. It took anyone 30 seconds to search the Facebook profile and realise it was of course fake, there was no Emma.
I got the impression from talking to JS directly via messenger he was exaggerating or simply making up a lot of his claims, be that his own ability or who he had coached. There was never any evidence for any of it. With Jan, you get the impression there's a hint of truth here or there but he's so engrained in his own lies, he can't separate fact from fiction.
The irony and upside is I found out about Letsrun and found a little thread called "Norwegian approach on lower mileage" and it was a game changer for me. So, in some ways I have Jan to thank, even if I wouldn't have dreamt of letting him coach me as the BS he was saying just didn't add up, or contradictory in nature, hence Googling him.
I know any publicity is good publicity, but I think Jan has reached a point where you search him out, it's almost all negative. The final lol moment for me was following the NSM thread and seeing him "forget" to log out of his main account and reply to himself, as if he was someone else. You have to have a strange mind to do something like that, let alone be caught out so hilariously and foolishly!
