We have had our Valco runabout 2 3wheeler for 9yrs now. It is still going strong although looking a little tired and weathered.
My DH runs with it and loves it, uses it most weekends. We also have the valco child seat attachment added on the front, so it copes really well with weight. It has a lock on the front wheel you can use for jogging and then take off when you are using it as a normal pram. The lock stops the front wheel rotating.
It has tyres that have tubes them in, great to run with, can be a pain if you get a puncture, we have only had one in 9yrs.
He can run pushing it with one hand, it also came with a jogging strap that you attach so you could push it forward and not lose the pram.
It was great going off road, so over grass areas and unmade road areas.

Two downsides to jogging prams is that they do not fit through a normal supermarket aisle, although they may have improved the designs these days and they take up alot of boot space, may not fit in a smaller car boot at all.
