first post here. i've been lurking for about a month or so, and i've lots of good info here to be really helpful. and now for my first question:
first some background info:
i've been riding a road bike for about a year and a half now. i started out commuting and then began riding longer distances on the weekends. so far my longest ride has been a century. after i completed the century goal, i kind of lost some of the drive to get on the bike and i started running more instead. i've decided that i'm going to do a marathon in may. before now, i had never been a serious runner and had never run over about 3 miles. i've found hal higdon's training guide and i'm doing the first beginner level as it is my first marathon. for now i'm only riding the bike one cross-training day a week and the occasional commute to work(10 miles round trip). after i run the marathon in may, i plan to do another in october. then, since i'm all ready running and cycling, why not swim as well, so i plan to start swimming in the fall and be ready for my first tri season in 2010. i do realize that i'm planning ahead pretty far, but it seems that long term training and goals are what endurance sports are made of anyway.
so here's my plan. right now i'm focusing on running, and only an easy-ish cross-training day on the bike. after the 1st marathon, i'll keep running, but i'll trade some of the shorter running days so i can start training seriously on the bike. then after october, i'll start swimming and i'll mainly focus on that over the winter, while cross-training on the bike and running. do you think it would be better to jump into the pool right away, or am i on the right track by taking it one at a time, then working on all 3 equally after i've focused on all 3 individually?
thanks in advance for the advice.
