It is a bit more than a week now, that I "can run again". It is still not very "funny", but it is getting better by the day. So the big test will be this weekend, I will try to run at least 25km and see if the legs can cope with it, at least running slowly... it is always quite difficult to start over again with running, other than cycling which is not so "muscularly demanding". Ran 4x 10-11km now and this distance at least is feeling Ok although still not like before.
