It's pretty easy to get onto the trainer for an hour or so here and there, but while interval work is critical for early season training, these short rides don't do much to lay down a mileage base. That's where Troy Jacobson's Spinervals series has been a godsend. Each winter, these DVDs have enabled me to extend my time on the indoor trainer significantly and as a result, establish base miles while the roads are still too hazardous. The discs I find most helpful for this purpose are the "Virtual Reality" DVDs that essentially follow Troy, and in some cases a few friends, over assorted iron distance courses filmed in mild weather. Staring at my laptop on the card table in front of the trainer is surprisingly absorbing as Troy barks commands regarding gears and levels of exertion. The courses and lengths of each of the discs vary, but each typically clocks in at about three hours and covers 50-60 miles. Today I rode in Madison, Wisconsin whereas last week it was Lake Placid, New York.
Nothing compares to simply riding on the open roads, but when the thermometer doesn't rise above 30F for weeks on end and snow storms blanket the roads, other strategies are required. While I'm carefully watching the forecast and hoping to get out to ride a 100K permanent next weekend, it's good to know that my training won't suffer if another storm heads into town (which is more than likely).
