HRM question

I've decided to regain fitness by doing laps of Centennial Park here in
Sydney, using my trusty old Polar s150 to set the pace. Even though it
has a bike mount (and gives readings for speed + distance), I've never
seriously used it on the bike, mainly for jogging.

So my aim is this: keep a fixed speed (between 25-30kph) and keep my
heart rate in a high zone (around 75-85% of maxHR). The course is quite
flat, with only slight uphills/downhills.

My problem is this: On the slight downhills, my HR drops off, and my
speed increases above the park speed limit (30kph). If I drop a few
gears and pedal like buggery my HR goes up a bit, but not enough.
On the slight uphills, my HR goes a little bit too high. Should I drop a
gear (and pedal faster), or go up a gear (and pedal slower)?

I tried experimenting over 10 laps, but could not work out the best
technique.

Anyone got any advice?

Even on shallow grades, the power required to keep you at the same speed
varies enormously. See www.analyticcycling.com and try out their Power
given Speed page. Quite simply, you can't keep your speed constant and
your heart rate constant on the Centennial Park circuit. Choose one or
the other...

PS. I was a little put-off initially because a cyclist acknowledged the
speed limit in Centennial Park

Speed limits are only for cars right? I mean, aus.cars there's no way
a puny _bicycle_ could break any signed limits... /aus.cars

LOL

the look of shock as i passed a woman in the left lane doing 72kph along
Rosanna Rd (past Watsonia Army Barracks) was hilarious

Speed limits are for hybrids with slicks only. Limits are irrelevant for
all other bicycles.

Except perhaps limits of friction which have now and again proven
important.

How do you know what I was riding? That's creepy.
Yes, I am saving for a decent bike, the old one got stolen.

Say what? I'm the limiting factor on my slick-shod hybrid, not any damn
arbitrary sign!

Got one!

Sometimes you just have to throw a line in...

I was only joking. The limiting factor for me is the slope of the hill -
the speed limit on public roads is usually too high for me to worry
about on the flats. (Though Centennial Park has a 30km/h limit)
