Should you race in the middle of marathon training?
It depends — not on the race, but on what it does to your training.
A tune-up race CAN help:
âś… Test your current fitness & reset your training paces
âś… Practice race-day routine, fueling, and pacing
âś… Get a hard effort without planning it yourself
âś… Break up the monotony of marathon miles
But it can also hurt:
❌ It costs you 7-10 days with taper + recovery
❌ A bad day can wreck your confidence, even if your training is actually going well
❌ If you're already barely staying afloat, one hard effort can put you under
Ask yourself before you sign up:
1. Does this race support my marathon goal?
2. Will I have time to recover before my next key workout?
3. Will the result actually change my training — or am I just looking for reassurance?
If it helps you fine-tune the next block, race it.
If it's a distraction, skip it.
I broke down the full decision framework in this week's newsletter — https://trainwithmarc.substack.com/p/race-during-marathon-training
