Continue to make longer rides with more elevation, progress. What's frustrating though is that my shoulders are getting quite tired on even shorter rides. Last year, pre-chemo, didn't have this problem. I have an Allant+ 8s which has a moderately upright riding position.
Any thoughts of what to do? It's pretty frustrating, because there are some longer rides my legs (and cardiovascular system and bike motor...) could handle, but my shoulders can't.
