US - State Record question - handicapping

When flying a US state record attempt for speed, I
understand that the achieved speed is handicapped. My
question is whether the minimum distance for that speed
record is also handicapped.

In other words, if I fly something with a handicap of .8,
can I file a 300K O&R speed record claim with a flight of
301 actual km or do I have to fly a minimum distance of
300/.8=375 km to qualify for the 300km O&R speed record?

Thanks
