nice to hear you enjoying it .. Between Day 3 to Day 10 .. running closer to 140 bpm is safer, however thereafter running closer to 150 bpm should be fine ..
ideally you would like your pace to be quicker from Day 10 onwards and at a similar pulse
as for the long run .. tuck another cycle under your belt and then look to slot the longer runs in
still plenty of time till Feb and still much more to come training wise before then
on we go
