I've recently bought a Garmin Instinct (bought for £220 but current price is around £270) as it had breadcrumb navigation following a gpx trail. It also has some cool features such as an in-built compass. I've only used it on a 31 mile 6 1/2 hr ultra (Punkpanther Welcome Way) and there was loads of battery life left after that (Garmin claims 16hrs). I had the optical heart rate turned on all the time & if you disable that then you will extend the battery life as well. DC Rainmaker has done a good review (https://www.dcrainmaker.com/2018/10/...th-review.html)

I am considering the Suunto Ambit 3 Peak, for a proven budget option, but interested that Mark G comment is to avoid older Suunto models.

Any other suggestions of previous years models that could do the job around the 150 pound mark?
Many thanks
