George Whitefield's Preaching Schedule

In his message at the Desiring God Pastors Conference John Piper took a glimpse at the life of George Whitefield, in this message he told of George's preaching schedule:

Speaking More Than Sleeping
"The daily pace he kept for 30 years meant that many weeks he was speaking more than he was sleeping. Henry Venn, vicar of Huddersfield, who knew Whitefield well, expressed amazement for all us when he wrote,

"Who would think it possible that a person . . . should speak in the compass of a single week (and that for years) in general forty hours, and in very many, sixty, and that to thousands; and after this labor, instead of taking any rest, should be offering up prayers and intercessions, with hymns and spiritual songs, as his manner was, in every house to which he was invited."

Make sure you hear that accurately. Many weeks he was actually speaking (not preparing to speak, which he had virtually no time to do) for sixty hours (60, not 16). That’s almost six hours a day, seven days a week, on the slower weeks, and over eight hours a day, seven days a week on the heavier weeks."

Who else thinks that this is absolutely mind staggering?
