Mid-Season Training Review: When and How to Adjust Your Triathlon Plan
Most training plans are written in January and haven’t been looked at critically since. By the time June rolls around, you’ve missed sessions, had a cold, squeezed in extra workouts during a good week, and raced events you didn’t expect to go the way they did. If you’re still following the original plan line-for-line, you’re probably not following the right plan for the athlete you are now.
A mid-season training review takes about 30 minutes and gives you a much clearer picture of whether your training is pointing you toward your goals — or quietly working against them.
What to Review
1. Training load vs planned load. Look at your actual hours per week across the last 6-8 weeks. Are you consistently hitting 80-90% of planned training load? If you’re regularly at 60% or below, your plan is either too ambitious or your lifestyle has changed — and you need to adapt it. Consistently training at 120% of plan is equally risky: it signals overreach and eventual injury or burnout.
2. Key fitness indicators. Review any benchmark tests you’ve completed — FTP results, CSS swim tests, time trials, or race performances. Is your fitness moving in the right direction? If your FTP hasn’t shifted in 10 weeks, something in your training isn’t stimulating adaptation. Either intensity is too low, recovery is insufficient, or volume is misallocated.
3. How you feel. This sounds vague but it’s critical. Are you looking forward to training? Does your body feel broadly healthy, with normal fatigue that clears with a rest day? Persistent fatigue, poor sleep, low motivation, and a raised resting heart rate are all signs of accumulated stress — whether from training, life, or both. These are red flags to address before they compound into overtraining.
4. Race results vs expectations. If you’ve raced, how did the splits compare to your goals? A weaker-than-expected swim tells you something different to a strong swim and a blown run — and adjusting training accordingly will produce very different outcomes in the weeks ahead.
Common Adjustments and When to Make Them
If you’re behind on volume: Don’t try to catch up with mega weeks. Add 10-15% to your planned hours for the next 2-3 weeks and gradually rebuild consistency. Trying to cram missed training into a compressed period is the fastest route to injury.
If your fitness isn’t progressing: Check whether your easy sessions are actually easy (below Zone 3) and your hard sessions are actually hard (above Zone 4). The grey zone — training at moderate intensity for everything — is the most common cause of plateau. Polarise your training for 3-4 weeks and reassess.
If your A-race has moved: A later race means more time to build — add an additional base week or two before beginning your race-specific build. An earlier race is more complex — if it’s inside 6 weeks, begin your taper earlier and accept you’ll race on your current fitness. Don’t panic-train.
If you’re dealing with a niggle: Treat it now, not after the race. Replace the affected sessions with cross-training at the same intensity and duration while the issue is assessed. Training through an undiagnosed injury is rarely worth the risk when you have a season to protect.
The 10-Week Rule
Whatever adjustments you make at the mid-season point, the fitness you build in the next 10 weeks is what you’ll race on. Not the fitness from January, not the missed sessions from March. Focus your energy on what you can do consistently between now and race day — that’s all that actually matters when the clock starts.
