It's only a partial fulfillment...

...of an earlier prediction, but I did bust a chain today, at Edgewater station about 6km from home.

I found that scootering at ≅14km/h on the flat and level was comfortable enough, and I could maintain a rough 17km/h with some effort. My walking pace was ≅6km/h, up from ≅5km/h a month or two ago.
