I got this on MV when I checked multiple years in interval training. It worked pretty well 
Check out our latest release, this has been improved.
Lol, I noticed! Already updated my season’s Plan Builder. Thank you for doing that for me 
With the new plans did my first V02 workout in XCO Specialty HV and finally it was a win! Struggled with the VO2 in the first 2 weeks on the legacy plans, but the new workout was hard but attainable. Previous XCO plans had me failing a 5.4 and 7.2 level workouts, which was a pretty high level after abandoning V02 work for 6 weeks (Plan Builder’s idea). Just completed a 5.1 workout and it was spot on! Well done @Nate_Pearson and @Jonathan, you have at least one happy customer with the new plans!
