Gave the running leg its first workout this evening.

I'm following a basic training programme with a view to completing my first 10k in a couple of months.

Considering I was trying it out for the first time, the Cheetah responded amazingly well -- and got plenty of admiring (or maybe just frightened) glances from fellow gym-goers.

The leg really did feel almost like the real thing -- flexible, responsive and remarkably comfortable. My hips and right knee started to ache a little after a couple of miles, but I think that's because the muscles need strengthening as much as anything.

It all bodes well.
