MellyW, I find the Strider Plus (4 wheels) great for walking. It goes well over grass, uneven footpaths, etc. Bit tricky on soft sand, but I don't go walking on sand much! I find it works well with walking. I'm not a jogger myself so have never jogged with it, although DH seems to enjoy doing bursts of jogs when we go for walks and it seems fine then.

Thanks Eluned! I am still undecided but am leaning towards the Strider Plus 3 wheeler. Concerned though about the weight/width - how do you find it?
