I’m 16 weeks out to my very hilly gravel race (UnPaved Pa.) I’m doing 90.8 miles with 6,209 feet of climbing. I’m coming back after a bit of a layoff due to work and vacation, so my CTL is a lowly 27. I have the 18 week sweet spot plan and Gravel Hilly Plan. My thought was to build up via the sweet spot plan for 9-10 weeks and then jump into the Gravel Plan leading up to the event. Does this seem reasonable, and is it as simple as just jumping from one to the other, or should I do some kind of transition between the plans?
