I am about to do my first bike race. 56 years old and it took until now. I quit smoking 2 packs a day almost 5 years ago when a doctor visit went bad...real bad. I started down the fitness road. I run. A lot. In summer I bike. A lot. I will never be fast, the smoking saw to that, but I CAN DO! So I do do. Running as fitness has a result of racing. There are a lot of road racing for runners. Not so much for bikers. Multi sport events...Triathlons and duathlons. If one can run swim and bike...there it is. Well I can't swim, not good enough to race, anyhow, swimming is also hard to practice in Colorado. A duathlon. replace the swim with a 5K run. I can do that. So Training has been fun. I am BRicking twice a week biking by itself once and running 5 times a week. a total of 30 running miles(or so) and 50-75 biking miles a week. A duathlon is different than a normal bike race: NO drafting (time penalty for doing so) one MUST be 3 bike lengths away from all others at all times except passing. 3 seconds to pass. (time penalty) No riding side by side.(time penalty) NO help of any kind during the race. (disqualify) The last one there...No help. This means if I get a flat I need to fix it myself. If the bike breaks I need to fix it without any help. I am planning on carrying : 1 spare tube 3 CO2 carts 3 tire remover levers 1 speed patch kit(in case I need more than 1 tube) That is it! Should I carry tools? I am thinking if the bike goes down that bad my race is over. But I am told it is "proper" to finish, no DNF's allowed. What you think? carry a (fairly heavy) multi tool? It is a race, after all.
