I would suggest starting with Couch 2 5km, this programme (available on a handy app on your phone) gets you going on a run/walk programme. This is the best way to build up without hurting yourself and don't be afraid if you need to repeat a week. In the meantime just try to build up some fitness by walking, walk to the shops or the park and chase your children round the park.
You don't need equipment to cross train, there are loads of videos of different length classes on YouTube which need no equipment.
