Hi,
We do regular 15-30 mile rides with our collie ( or 2 x 12-15 mile day rides at a weekend as short rides) – 5 years old and she loves it – she yelps the house down when she sees the bikes or loading the van – she was started out at 18mths and built up over time – apart from a 6mth lay off due to injury ( hit a hidden fence post in the snow at full tilt = 2 hour carry across my shoulders back to the van ) she is good to go – just dont thrash them on a road – ours will trot all day at 7/8mph and top out 25/28mph when given the secret turbo word….
She has done a lot of trails – all of exmoor / quantock / mendips ( 6 – 8 hr days max 40/45 miles ) plus big hills like helvellyn / skiddaw / high street / snowdon / cadair idris / a fair few munros etc with her and all the trail centres I can think of… Regular on the long mynd etc !
I suggest getting a high viz coat as that really helps other trail users / car drivers / bike / horse riders see her running at the side of us.
She is very well trained ( think one man n his sheepdog style ) to the point of asking for a positive command to cross a trail junction etc.
A fleece coat is a bonus at the end of a ride to keep them warm and dry off.
Ruffwear kit is great – she has a harness ( helps with lifting over styles or up steep faces when hiking) and booties / panniers too for long days out… Second keeping them well watered – a fold up bowl is useful as is a toy for when you stop for lunch…
Oh, get a tick tool as they will pick them up… learn some doggy first aid and carry some vet wrap etc and learn the signs of an adder bite and enjoy riding with your dog.
I prefer riding with ours to most humans I know…. she is certainly quicker than most ! Yes I do carry her poo out too…
