Is the Pope Catholic? I don't think these guys know what a one-path is. Though usually, very wide trips in turf races are the rule rather than the exception, as the riders are all looking for the fast lane. It is really odd to see some races break out into separate running groups across the track in order to stay on the best ground. Five and six wide trips, and higher, are not at all uncommon. But again, there are very few dirt races here in Europe, so the emphasis is on finding the express lane, not on saving ground. But this generally doesn't apply on dirt, except of course with the occasional rail bias. So I would say yes, running on the outside would be SOP, but is usually seen mainly in turf races.
