There is a lot of climbing to this profile with only brief periods of “downhill” recovery. Most of the climbing will be done at a moderate intensity. On the first three hills, you will guide your riders to push hard to threshold (Zone 4) at one of three different parts of the climb: beginning, middle, or end. For the final climb, you will decide which of these three segments you preferred pushing, and repeat it.
There are four parts to the four hills riders will climb. It’s very difficult to push above threshold for all three uphill phases on long hills, and it’s impossible to push hard going “downhill” on an indoor bike. Riders will push at threshold (Zone 4) during the crest, climb, and build phases on three different hills, while working in Zone 3 for the other phases. This will enable them to determine when it’s best for them to push up a hill.
And just remember, what goes up must come down, so enjoy those recoveries!
