Uphill Battle starts off with 3 sets of 5 mins right below Threshold (95% FTP) featuring a 30 second ramp-up to finish (from 100% FTP to 150% FTP). After these, we will be moving onto 2 sets of 30/30s (30 seconds work, 30 seconds rest). The first set is done at 130% FTP for the work interval and 70% FTP for the "rest". The second steps up the ante a bit to 140% FTP for the work interval and 60% FTP for the "rest". Do you have what it takes to finish it? I know you can!
