Read the FAI sporting code. Section 3. http://www.fai.org/gliding/sc3.
Actually read it many times.

Yes you need to declare the triangle. Which means you need to declare
the turnpoints. Now wether you declare the start and finish is a
different question.

If you don't declare a start and do a start off tow you need to finish
within 1,000m laterally of the finish to be considered a closed
course, and since your undeclared finish will be by landing you then
have also introduced the unneeded complication of not being able to
start off tow more than 1,000m above your landing point. But why do
that? You would normally either declare a start/finish point and two
waypoints or less likely declare a three waypoint triangle with remote
start finish - this might be done for also capturing other flights
claims withing the same flight. With a declared start/finish, all you
are watching is the 1,000m total loss of height during the task and
forget anything about height above ground (except just worry about
staying above ground during the flight...).

You also need to get the FAI triangle distance and ratios correct for
a record flight. See SC3.

There are many more things to worry about, these questions indicate
you likely need to read SC3 a few more times and then you'll be able
to come up with some really good questions to worry about. :-)
