My heart stays relatively low, but my quads have a lot of burning.
What's your typical cadence when climbing? And are you "saving" a bailout gear? A lot of people like to climb in their second or third smallest gear because they like to know that they still have somewhere to go if it really gets ugly. The problem with this is that it generally makes the climb harder, and by the time you hit the bailout gear your legs/lungs are wasted.
Rather than trying to "save a gear" (if you are - it's pretty common) try to select a gear that allows you to spin at a comfortable cadence - ideally in the 80-100rpm range. The statement "
my quads have a lot of burning" indicates to me that you're pushing too big of a gear, relying on strength to get over the hill. Shift up and make it easier on your legs.
Another thing to try (and work on) is your standing climbing. Triathletes as a general rule tend to favour seated spinning over standing, but standing is an excellent way to climb - and is sometimes your only option when it gets really steep. If you've trained your standing climbing, it won't put a huge tax on your legs.
If you've run out of gears, compact cranks may be something to look into. Especially as a smaller woman, most road bikes are WAY over-geared for a non-elite cyclist. I'm a fairly strong guy, and have been a (most definitively non-elite) cyclist for ~16 years and I really like my compacts on the road bike.
Climbing is a little bit like running in that you have to do it
a lot to get better at it. You've got the right idea, riding frequently and climbing a lot. Keep it up.
