I'm thinking of starting a training program on the road bike over Autumn and Winter, the first phase of which mainly involves weekday rides of 2-3 hours (at various HR levels/cadences) etc. with longer rides at the weekends.
My question is whether I could split the week day rides over my commute without losing too much of the benefit? This will most likely manifest as 45 minute AM and the rest on an extended route home. The alternative is to ride the full session in the afternoon and use AM commute as a recovery (which will probably push AM time to closer to an hour).
I appreciate I will probably lose something in increasing endurance, but I'm not too bad (relatively speaking) in that respect and looking to bring my 'default speed' and power/cadence output in line with my endurance.
For info I am generally less fit that the average person, not training for a particular event/discipline have chosen road training due to not wanting to lose the fun from riding off road and for simplicity of longer routes with relative ease.
Sorry for the waffle, ta in advance.
