If it's only about the H1 - if you look at the source the H1 tag is commented
Example; http://runforcharity.com/start-to-run/get-off-that-couch/getting-fit-for-a-marathon - H1 tag in source:
Seems more an issue with your developers than content.
The main title on that page is GETTING FIT FOR A MARATHON - which is the H2 title. I would change this to the H1?
