DigiHUD on the cheapest prepaid phone out there.  At one point I grabbed a Samsung J3 Orbit for $30.

That’s what I was thinking - I have a really old Motorola and I tried a few apps but struggled finding one that captured top speed - I’ll have a look at that one 

thanks @speedy_w_beans

I'm using an old Garmin Forerunner 101 training "watch." If buying new the Garmin watches are above what you want to spend, but there is a pretty good used market out there.

Something to think about.  Most cheaper GPS receivers only sample at 1-hz, meaning they will only collect positional data every second.  Unless you hold your peak speed for over a second (probably 2 seconds) and get two data points at that speed, I believe it will calculate a speed less than your real peak.  I noticed even the SkyRC only has a 1hz sample rate.  There's 10hz and faster receivers, but they'll obviously be more expensive.
