Narrative:

We were on takeoff roll in ZZZ with a full power takeoff for gusty winds when at about 100 KTS. I noticed a fairly strong odor of 'dirty socks' or 'electric heater.' we continued the takeoff roll and by the time we [were] airborne and I had selected the landing gear to 'up' the smell had gone away. I asked the first officer if he smelled the odor and he stated he did; but that he didn't smell it anymore. We did not run any QRH as by the time we recognized an odor; it went away. We continued normally and during our lavatory break in the middle of the flight; I asked the flight attendant if he had smelled the odor on takeoff. He stated he did and did not communicate any more concern to me. The flight continued; [we] landed normally and we arrived at the gate early. We then continued to switch aircraft in ZZZ1 to complete the last leg of our trip. Myself and the first officer felt fine the rest of the trip.
