Looks like a fun plan for next year! I'll be watching your log develop.
Sounds like you had a pretty typical programme for 10 years ago. We were all doing more more more more! Some people can handle that well and race very well on it and can go for years, others cannot. It's hard to know if its actually really optimal for anybody tho, eh? For me, I learned a long time ago I cannot do that on the run or I fall apart.
Do you tend to write out a programme ahead of time or make it up as you go?
The fun races are a great idea and help to keep things in perspective. Too often in "modern" IM training people race one or two races/yr and that's it. As you say, it can make it a chore, and if those one or two races go badly it can be tough on the head!! In old-school training I think we tended to over-do things, but at least we had fun doing it.
