Is a 3km time trial okay? Yesterday I tried a 5km TT and was doing pretty well, but around the 3km mark I started to struggle.

I checked my heart rate and was scared because it was too high (actually, analyzing other races, it was just right for the type of effort), so I gave up.

For the future, since I find a 5km TT mentally too challenging, would a 3km TT be enough?

For Context this is my first TT since I started NSM 6 Weeks Ago .
