Are you trying to “solve a problem” for her?
I mean it in the nicest way, its what men do, but you have discussed this with her haven’t you? I mean you sat together googled “mtb coaching for beginners” and she’s dead keen…right? And you said, I’ll just ask them on Singletrack, they’ll know.
I would like to see her more confident on the road too, as she rides every day.
When I can be bothered, I persuade my mum to come out sometimes, she even rides to work occasionally if the weather is ok, and she has a great time generally, but she wouldn’t want to go on a skills course TBH
