From Baloh's website, the email confirmation from the Ultra Marathon Cycling Association (UMCA):

24 Hour
561 miles 3028 feet = 561.5735 miles = 903.765 km
23.40 mph average speed
Note: Great effort by Baloh to surpass the 900 km mark in 24 hours!
This replaces the record set by Julian Sanz Garcia, age 35, in November 2008 of 481.56 miles.
#4
1000 KM
27 hr 31 min 9.52 seconds
22.58 mph average speed
Note: This replaces the record set by Rod Evans of Australia in 1994 of 29 hr 12 min 33 sec
Four new records: This is one of the greatest one-day (plus a little) rides ever!

It's possible these are track-only records. Anyway, a bit of a mess!
