If you\u2019ve ever been a runner, swimmer, or rower, you\xa0might be\xa0familiar with the concept of\xa0two-a-days\u2014individual\xa0workouts\xa0separated by hours\xa0within a single day, most typically one in the morning and another in the afternoon.\xa0\n\xa0\nIn cycling, two-a-days have not had\xa0as much\xa0traction. However, that\u2019s starting to change.\xa0The science\xa0is new, but many coaches, including our guest Neal Henderson, director of sport science at Wahoo Fitness,\xa0have been putting two-a-days into practice for years, with a lot of success.\xa0\n\xa0\nIt brings up two big\xa0questions:\xa0Are two-a-days as\xa0effective as one\xa0single\xa0long ride\xa0at generating adaptations? That is,\xa0can they serve as\xa0a\xa0substitute?\xa0The other, in some ways more interesting question,\xa0is whether\xa0two-a-days\xa0have\xa0benefits\xa0that you can\u2019t get any other way\u2014for example, through glycogen depletion.\xa0\n\xa0\nAgain,\xa0the science\xa0is rapidly evolving,\xa0and today\xa0we\u2019ll\xa0refer to\xa0new research that opens the door to a new line of thinking.\xa0And we\u2019ll also talk extensively with Henderson and a host of others about the practical ramifications\xa0of two-a-days.\xa0\n\xa0\nOur other guests include\xa0WorldTour\xa0rider Petr Vakoc, racer and coach Jen Sharp, gravel racer Ted King, physiologist Jared Berg, and pro mountain biker Payson McElveen.\xa0\nLearn more about your ad choices.
