As usual, depends on budget. Fixed front wheel is a must IME. If you want to do some proper running then something with big wheels, I have some friends with one of these and they love it. They’re ‘proper’ runners and do some serious mileage.
I have a barely used one of these in the garage. No big wheels and no adjustable handle so probably no use to you, but a very nice piece of kit. It’s the older model with a hammock seat so better for off roading. LIttle’un used to quite happily sleep through a 10k run. It’s probably a bit more practical than the bigger wheeled versions if you want it for everyday use also.
Bought when the first was about 4 months old, 9 months later we had to get a double buggy so it was used for 6 months tops. Been meaning to Ebay it for ages, if it’s of any interest mail me (address in profile)
Edit: Just checked the Mountain Buggy link above, it lists a handlebar extension so might suit?
