I own the Chariot Cougar 1 (for 1 child), bought for biking, but we actually use it for jogging a lot as well. I wanted to be able to go mountain biking and on dirt roads, and this was the only trailer that has suspension and I found that people had actually taken off pavement. Although I haven't yet taken it off pavement, I'm sure it will be great for that. It is very expensive (about $700 for the chassis, jogging and biking attachments), but you might be able to find a good deal on the 2009 model, or get it cheaper on eBay. I saved several hundred dollars by getting the previous model. It really holds up, I have used it for triathlon training, so my son can be with me when I train, using it almost every day for several months. If you plan on using it a lot, don't go for a cheap one, you will probably end up just buying another one. Also, the resale value on these holds up really well, you'll see if you check eBay. The Chariot Cougar is a cheaper version, no suspension, and Burley is another really good brand, not as expensive (although still several hundred dollars), but something to look at if you will be using this a lot.
