One ‘present’ I received during the bike ride was a knee injury that seems to be worse than I initially thought. My knees had been hurting from day 1 and it got progressively worse. The pain was especially bad in the morning, but normally would get better while riding for a while. But climbing mountains (which is what we did about 50% of the time) was still very painful. However, no reason to give up of course.
I thought the pain (mainly on top of my right knee cap, but also below my left one), would go away after a few days. That’s not the case: when I walked up the stairs to my 7th floor office every step hurt, and I now consider taking the elevator from tomorrow onwards. Yesterday I went for a run, but had to give up after about 30 minutes because my knee was interfering. I think I will take it slow for a few days, I don’t want to make it worse. Right now I can hardly get out of a chair without pushing myself up. If anybody has suggestions what to do, let me know.
