I went on a longish (30min in labour, more like 18 if i hadn't been, even in late pregnancy - bear in mind that you might need to stop when you contract) walk in early labour and it really helped get things moving for me. My ctx went from 1 in 10-12 for 40 to 1 in 5 for 90 BUT it was still another 7 hours before i gave birth.

I didn't find labour to be physically exhausting so much as mentally enhausting and the walk actually helped with that.

Take someone with you who you can lean on/hang off when you contract, and have a person at home with a car and your bag in it to follow you (you can text when you're nearly there for them to set off so they don't arrive 40 mins before you). Lol. That way if you aren't very dilated you can have a lift home again if you want one.

If i were you i'd try a walk 10mins round the block when your contractions are enough to make it hard (but not impossible) for you to talk through them, and see how you're handling it. If it feels good then begin your walk to the hospital with your trusty assistants good to go too. Breathe deep and slow through contractions. If you get the urge to make loud noises during a contraction call for the car. If you feel you need to push call for the car. If you feel tired call for the car. If you don't feel any of those things, enjoy your walk and your birth
