Thanks my friend!

Yeah, I didn't expect that dip to occur yet but it did, still feeling like 40% of the intensity and that still hurts but so much more manageble than during the last week. Like you say I have this haunting me about every year/two years for the last 20 years.
(Working on a structural solution and a safety net to break that spiral earlier - so it will be alright!)

While my oldest is still sick, my wife and youngest seem to be all good again! For me the sickness seems to be a common cold. Which will be long gone at the race!

On the vaccine, I experienced something similar after my second shot aswell, it lasted until I actually got COVID and recovered from it. Strange stuff!
Does that higher heartrate translate for you into getting tired earlier? Or in simply burning more calories with lower intensity?
