Last week we had our family MTB trial day around Dalby Forest; we were a bit late so our 'full day' was 4.5hrs.
I hired a
Scott Tour 29er, and really liked it. Older mini ao and I did a fair bit of red trail which was excellent fun, but takes a lot longer than you think and I reckon one needs most of the day to do it all. Never got round to trying the world cup course. Some of the red trail is pretty technical, and I did quite well although there were some downhill sections were I though 'I probably could, but maybe not...'
The bike barn seem pretty organised, and one can reserve bikes without payment - but giving a time of arrival. If you don't turn up within 30min of stated time they may be reallocated, unless one rings them to give revised time of arrival... This worked well, as if it had been chucking it down with rain we may have given it a miss.
