I managed a reasonably respectable 24,327 Km, just short of my target of 25K for the year on the Strom.
In my defence I did have 2 lengthy stays in hospital, and a month out of the country when our youngest was representing Australia as part of the national gymnastics squad at the world championships in Birmingham in November.
I haven't a clue what I covered on the other bikes, but would hazard a guess at between 2,000 and 3,000 Km.
