I was thinking the same.... I felt like I wasn't even the standard of a beginner!
Bought myself an old (maybe 12-16 years old) Diamondback rigid mountain bike off
ebay for a bargain price, just over a month ago. Seems to be put together with some nice Shimano components and while well used, it's been very well looked after.
Living on a hill, it means wherever I go it's going to be hard work getting back, hauling my 18st frame up... but started off doing a few 3 milers, building myself up steadily and last Sunday did a good 17 miler, that I felt really proud about. On Monday in my lunch hour did an 8 mile non-stop and felt good about that too! Feeling good about it all.
Hoping to get some longer distances and try for a 30 miler, and attend events...
Loving it!
