As is often the case, many ups and downs, with a mixture of pleasant surprises as well as disappointments. (I was tempted to write "bitter disappointments," but I realize that in your 70s if you are injury free, putting on a race bib, and still having adventures … count your lucky stars.)
On the positive side of the ledger, I met or exceeded three major goals: overall volume of training, total number of days on snow, and logging adventures in Sierras, Tetons, Switzerland, and Norway. Adding to this, I logged my longest MTB ride ever(67k). Strava verified that the 41k I skied in the Birken was the longest in over a decade. Moreover, I finished third in my age group in the very competitive - gut busting - Broken Arrow VK.
