Thats quite exciting Feanor.
I'll be working form home for the foreseeable. I'm trying to think of a wee run to mimic a commute (e.g., long way round to the co-op) so I feel alive by the time I sit in front of my computer. It makes a huge difference for me. I have been commuting in Edinburgh where traffic was used to cyclists, and I had bus lanes, etc. Around my home, the traffic is truly shit.
I think that it's really hard to do artificial miles on a commute.
I used to ride 60k over the CoM to Montrose (and then the same back) a couple of times a week, but then my workplace closed down.
My new work was in Banchory, which was the first 16k of my old ride in, basically the warm-up.
I decided I'd try to replicate my old commute, and get up early and ride to the top of the CoM and then back down the way I'd come, back to Banchory.
That happened a grand total of about 3 times.
I just couldn't motivate myself to put in those artifical miles.
On the ride to Montrose, they were necessary miles and elevation, but here they were not.
It just didn't work for me.
