Plan is to do 1 minute ladder:

60 seconds sprint, 60 seconds rest
60 seconds sprint, 50 seconds rest
60 seconds sprint, 40 seconds rest
...
60 seconds sprint, 10 seconds rest
60 seconds sprint, 20 seconds rest
...
60 seconds sprint, 50 seconds rest
60 seconds sprint
DONE

Including warm up, should be about 30 minutes total. If you plan to come, please reply to thread so I know how on time I have to be :)

Too bad I won't be able to get down to Kezar to make this - looks like a good one. Have fun, should be a lung burner.
