After insanity...

logdunne

Hellos,
I am currently on my recovery week between months of the insanity workout. I am already looking to get something to go onto after insanity, just wondered if there are any cracking suggestions out there?

A bit of background:

I run, I would like to increace speed and endurance in that, so something to help there would be good.
I have done 30DS, find it is no longer much of a challenge and is too short- ideally looking at 40-60 min workouts.
I have looked at p90x but the cost is offputting and second hand copies seem to retain thier value :-(
I like the format of insanity, I also like that it contiues to kick my *kitten*.

Any suggestions would be appreciated :-)
