No, however its flat around here and not an issue to ride steady for hours and hours (for example see my ‘Strava moose’ post here Too high intensity for base training - #19 by bbarrera).
I respond to volume. Recently did an HC climb after a couple days not feeling well. Here is 5100 feet of climbing with only 100 feet of descending, it was literally straight uphill for 4+ hours and I just wanted to get the work done without worrying about hitting the 180-215W target (in green on chart below) in plain sight on my Garmin:
lots of z1 power, from the past I knew that length of time and relatively low cadence were going to deliver adaptations. Sure enough, within 10 days I was already seeing adaptations and highest power-to-HR of the year on my two hour Tuesday ride (and it was very warm on that day). And last week (about 4 weeks after the climb), I hit all-time power-to-HR on a 2 hour endurance ride in the gym, partly because the average temp in gym was around 65 degrees / 18C and a LOT lower than my usual 80-100F / 27-38C outside summer rides.
