Triathlete's Training Bible - 3ed worth it?

Friel claims lots of new material. Anyone else think the 3ed is worth an upgrade? Will I shave 10 seconds off my 10k?

I generally liked the last edition, the caveman diet section notwithstanding.

There’s a supplemental version coming out, so you don’t have to buy the 3rd edition, and try to fish thru it and see what all was updated, etc. Should be available by next month.
