Winning a record six Tour de Frances isn't enough for Lance Armstrong, who may try for the Hour Record at the Seven-Eleven Velodrome in Colorado Springs.
Armstrong would ride on the banked track for 60 minutes to see if he can best Great Britain's Christopher Boardman's record of 30-point-721 miles set in 2000.
Armstrong's coach Chris Carmichael says the seven-Eleven Velodrome is the leading track for the attempt, which would probably happen in late 2006.
Carmichael says he expects a decision on a date and location of the record-breaking attempt within eight weeks.
The velodrome would need to be covered and resurfaced, which Carmichael estimates would be "a seven-figure project." The city owns the track and leases it to the U-S Olympic Committee.
