I can’t offer any direct workout suggestions, however if you’re riding unstructured then why not just ride for fun? It sounds like a good opportunity for such
I’m going to try an RPE on the commute to try and free up that time. Well it isnt actually wasted after 6mins of a warm up, its a tempo to threshold session for 26minutes until the other end when its 6-7minutes through traffic but AI will take no account until PL2’s are launched. So I’m trying a 30minutes RPE alternate for my workout and hopefully that will fit in there. Bear Creek-5 and we will see if that becomes a favourite.
