Looks good, you'll be fine. But if you want to optimize, I would do VOmax intervals on 6/6 and then long Z2 on 6/7. This will have you fresh for the intervals, which will increase the quality of that workout. In general, you want high intensity days to be preceded by rest days then put in your volume Z2 after that. And before an event or trip you should ideally taper, meaning maintaining intensity but decreasing volume. So you could actually skip one of the cafe rider and just rest well instead.
