I just completed my first tri season with three sprints. Now I am going into my first off-season and I would like to start the off-season with tests that I can measure against over the next few months. I also just started reading The Triathletes Training Bible where he lists a bunch of different tests. The problem is that i don't have an indoor cycling trainer or anyone to come and record heart rates and paces. what would be a good test or two in each sport that I can do on my own and repeat every few weeks to check progress?
Swim: Time trial. I suggest either 500m/y or 1000m/y depending on where you're at simming-wise
Run: 5k race. Usually easy to find one of these somewhere nearby almost every month.
Bike: Time trial. Since you don't have a trainer, find a route of ~10mi that doesn't have any/many stops. Flat & straight out-and-back would be ideal. Would be nice to have power since conditions can affect speed quite a bit, but just try to note if the wind was unusually strong or something.
