Nah, in conclusion innerleithen red is actually pretty good but the area is full of fantastic riding so it's hard to find as much enthusiasm for the merely good.
Positivity- How to make inners red better- add a dose of Alistair Lees.
After the first steppy climb (Stell Burn Climb), instead of carrying on up the red climb, keep going up. Turn left on the fire road through the (open) gate then up the old XC climb (beside the downhill pushup). Keep going up, it joins the pushup (which does ride, but is a bit unpleasant). Follow signs for the Matador, all the way to the very top of Plora Rig.
When you reach the trailhead for Matador, keep going straight, down the grassy/heathery path for a very short distance. Take the first trailhead on the right. Enjoy. When you hit the fire road, you need to go slightly left then right onto the next trail, nice and easy to spot. Then this eventually hits the original red climb, right before the quarry. It can be downright treacherous if it's wet but is one of my favourite descents anywhere.
This adds about 200 metres of climbing, some of it nice, some of it not. It does miss out a reasonably nice bit of red route climb, but no descent. But it gives you a massive amount more quality and variety for your lap, without taking away anything, and since the red's short, it's still pretty much a normal day out.
(you can also easily add a downhill Middle- when you reach the end of Oh Deer on the red, instead of going down/along the fire road, go up. When you reach the 3-way junction, instead of going more or less straight on (back to the top of Plora Craig), double back, keep climbing. This is about an extra 100m of climbing all on fire road. If you want to rejoin the red, just pick a downhill trail (Gold or Cresta probably, or the Deerhunter which is the one which has a signboard but strangely no name on the sign), head down it til the next fire road, turn right and spin along til you reach the top of Caddon Bank- again you've missed nothing out)
