airdyne to hell and back

today's workout was called something like "to hell and back". John bought an Airdyne over the weekend and we got to use it in today's workout. its brutal. seems easy at first but there's no recovery motion in it so its all work the whole time. its amazing.
warmup
5minute on rower easy
2 minute on airdyne easy

Workout(for time. not easy)
50meter row
40meter airdyne
30 meter row
20 meter row
10 meter airdyne
20 meter row
30 meter row
40 meter airdyne
50 meter row.

I think the workout is named wrong. Should be called to heaven and back. the 50meter sections are the real hell. the low numbers are not so bad. i think this kind of stuff is going to make the marathon a lot more fun.
