Roadbike…. how big are your tyres?
Disclaimer i was on foot.
Disclaimer 2. If its the track i think you are talking about that runs between loch if the lowes and st marys…
Its a proper track up to the forestry bit loose but you’ll probably be okay at low speed.
Not sure about in the forestry as it was detoured due to felling last year and we were never planning to shoot out the other end instead we were planning to loop back down after a stretch of the suw.
I’d certainly give it a crack mud wont’t be an issue i’d have thought even without the fact its drysabone. Its a bit rougher at the start climbing out until you pass the farm on the right so dont give up too early. Worst that happens is you turn round or push.
