That is awesome – remember the kiss principle “Keep It Simple, Silly” Do not push it – the PT really paid off and you do not want to throw that away. Very slowly but surely keep at the easy pace over short distances. At the slightest tweaks or twinges really evaluate things and err on the side of extreme caution.
You will know when the time is right to start stepping it up.
Good luck in keeping it simple – keep us up to date.
