In case anyone didn't see the previous thread....
From Toks...
"If speed is what you need? Sat 6th May: another 90 minutes of, threshold-raising, super-friendly, thru and off style chaingang activity - the ride will be punctuated with a five minute catch ya breath periods every twenty minutes or so. If you're not on a long hilly one - see ya this saturday!"
Perfect for anyone wanting to jump from 18mph groups into the faster ones this summer - it's not much quicker but much more organised.
Highly reccomended
