Weekend modifications

I am on the 16 week sweet spot plan and have been doing it on my smart trainer. Due to family obligations and travel, I have been unable to complete the 2+ hour weekend rides (not to mention they get really boring). I am also an Optimize subscriber and have sent two messages via Optimize and I have not received a response so I don’t know if they aren’t going through or what the problem is. Please let me know some alternatives to the long weekend rides that I can do during the week as I often don’t have access to a bike on our travels.

Mark - apologies, we have not seen any message from you come thru - are you sure you hit send or anything else?
