SS - my marathon qualifier for Comrades was 3:47. RR has about a 3:40 I think. Neither of us have been under 11 hours in either direction. While I am sure it's do-able, I think the guides that suggest you can get under 11 hours with a 4:15 - 4:30 marathon are wrong for most people.
The biggest tip - most important thing - to ensure a finish is not to stop, Ever.
