Beautiful day Sunday, was cruising on the local greenway trail. Many dog-walkers and joggers out. Lots of children and families on bicycles. I was taking my time, being courteous in passing, and enjoying the day.

I came up on a family of four - mom, dad, boychild and girlchild between them in line, going up one of the larger hills on the path.

After waiting for them to pass an even slower group, I called out, "bicycle on your left" to let them know where I was, and slowly started to pass. I'm busy paying attention to the wobbly children beside me, going slowly, when I hear a yell. "Stay right!" A rider decked out in team gear on a racing bike was coming down the hill a pretty good pace, perturbed with my position on the trail. There's enough space, so I pull in line with the family, in front of the children. I get a sarcastic "Thanks" as the lady on the racing bike passes by in the other direction.

It got me a little upset. On a MUP you're supposed to stay to the right - but riding carefully and cooperatively is important. I expect someone cresting the hill and seeing the traffic to slow down and make allowances for the passing motion that commenced before she was visible. This is not a highway, but a shared recreational facility.

On a mountain bike trail, the rider going uphill has the right-of-way. Does this sort of though process transfer to a MUP? Or was I totally in the wrong. I feel like if you're worried about maintaining speed and road position, you should get on the road, as the MUP is redundant to the local highway.

Anyone else have similar experiences?
