I contacted the Ride to Live organisation, last year, re. a “non-tarmac” training course, but was told that their thinking/planning revolved around tarmac accident statistics, so a non-tarmac was unlikely in the foreseeable future. This struck me as being a bit short-sighted, because of the huge number of public non-tarmac roads on both islands, and that accidents on these roads can still result in injury requiring treatment.
Shame, really, since the organisations bronze, silver and gold courses are really worthwhile.
Maybe more pressure from adventure bike riders for non-tarmac courses would lead to a change in thinking!
The local Ride to Live organiser was more than willing to run such a course, but there’s no current support from the organisation.
