Someone asked at the press briefing today about whether you could go out to exercise and take the kids out separately later. They said that you should only go out once a day so should combine your exercise with taking the kids out. I went out for a run this morning then later took to the kids for a walk to the allotment to pick veg. I'm certainly not going to get my heart rate up enough for it to be useful CV exercise if I have to to it with a 2 and 4 year old. I'm not really one for rule breaking but I also don't want to quit running.
