Will you be down there for the big race, Dave? Muffin's doing it, subject to ridding herself of flu, throat infection, sciatica, ITB strain, strained periformis, strained deltoid and... erm... no I think that's it.
You're in luck. Very good swim and run sections at Chester. Well coached and inclusive.... even the track session is friendly! The bike section has traditionally been a bit crap though... the Club Captain used to lead one ride from Blue Moon that's not especially popular because it's a bit hardcore. Unfortunately, he got seriously wiped out by a car just recently, so I'm not sure what the provision is. Other bike ride leaders weren't so common, but that might have changed recently.
Suggestion... Deva Tri in two weeks and they're crying out for volunteers because it's such a big event this year. Throw your hat into that ring and it'll break the ice nicely for you. I think I'm on "carparks" at 05:00
