A while ago I got the Holux GPS Sport 260 here it has been great for my needs, you can setup routes to follow (although not using trails / offroad as the system uses google maps) and of course download all of your data into the app to analise it / upload to online things such as Strava. I didn't go for the cadance / heart rate monitor as at the time I didn't think I would need them but I think in future I may upgrade.
The same thing but with cadence, HRM & speed can be found here for £144.95
You can get extra bike mounts for under £10 so it's easy to switch it around

this looks good for only 55 quid
do you have one?I wholeheartly agree
Can you add routes to it with waypoints /directions or does it just log your ride? I am thinking it might be use for a sportive ?Yup, I've had it at least 18 months and it has had a tough life, but is tough as old boots so it doesn't matter. The software is reasonably good but more importantly you can easily export gpx files for endomono, strava, google maps etc.
I use my holux every day and only need to charge it about once every ten days.
