Managed to backup up yesterday's bike-run with another one today. Up for the bike was workout 4 of the Zwift Academy and again, I fared better than I thought I would. The anaerobic efforts looked scarier on the plan than in reality but I'm not going to get cocky as workout 5 looks even scarier. The 1 minute 150-160% FTP intervals look tough. After a couple hours recovery I knocked out 5k in a ramped increasing effort. Felt pretty good and it's been a good weekend of training.
