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?
