A list of pre-registered riders can be found here (it's a bit more inclusive than the numbers below which include only riders who listed their club affiliation with a US club).
As of April 17, the ACP has said that registration is closed and that no new spaces will be opened up for riders who could not pre-register.
The following data has been compiled by Mark Thomas, who again for this edition of PBP is working with the ACP to help troubleshoot registration problems for American entries. NB: these numbers are not official, and certainly subject to change as pre-registration completes and when pre-registrations are converted to final registrations.
The US currently has 589 pre-registrations (73 F, 516 M).
By time limit:
80 - 71 (5 F, 66 M)
90 - 402 (55 F, 347 M)
84 - 116 (13 F, 103 M)
