I’ve had search but I can’t find documentary film anywhere. Does anyone know where I might find it?
Unfortunately, it doesn't seem to be available.
I followed the link on her own website to YouTube and checked the links given there - a pay for stream service - and they are all dead.
Perhaps contact her and ask?
If you want a suggestion for a woman's bike adventure at a completely different pace I'd suggest Dervla Murphy's "Full Tilt: Ireland to India with a bicycle". An amazing read and a glimpse of parts of the world that we wouldn't recognise now.
