I'm looking at getting a running stroller to use with our twins this spring, they'll be 9 months. I've been looking on craigslist for a while, and I've narrowed it down to the Baby Trend Expedition double jogging stroller. The stroller I'm looking at, I think is an older style, with a fixed 16" front wheel, as opposed to the current style having the option to have fixed or swivel, with a 12" front wheel. To ME, it seems having the larger wheel would be desired. Yes, no? It is a drawback not being able to hav the a swivel though. I can get both versions at about the same price. I do street running up 10ks. Any ideas/suggestions? Any input on this model? Also, any input on bf running with a stroller?
