Groin / abdomen
Groin strains, sports hernia, and core weakness
Sudden sprints, hills, and weak deep core muscles load the groin and lower abdominal wall. Sports hernia (athletic pubalgia) and adductor strains are common in men returning to sport or ramping speed work too fast.
Sharp groin pain with acceleration or cutting motions; dull ache in lower abs after runs; pain coughing or sneezing; or one-sided testicular ache that doesn't improve with rest.
Signs to watch for
- ·Pain at the pubic bone or inner thigh when pushing off
- ·Tenderness in lower abs — not just the groin itself
- ·Pain that worsens with sit-ups or coughing
- ·Testicular pain or swelling — always get this checked promptly
- ·Nipple chafing or bleeding on long runs (common, preventable)
How to avoid
- ·Sprinting or hill repeats before your easy base feels solid
- ·Only running for 'core work' — planks and dead bugs protect the groin chain
- ·Ignoring testicular pain or swelling — torsion is rare but urgent
- ·Running in cotton shirts on long runs without nipple protection
How to fix / recover
- ·Relative rest: cross-train (bike, pool) while groin pain settles — don't test it every run
- ·Gradual return: walk-run, then flat easy miles, then hills last
- ·Adductor and hip strengthening — Copenhagen planks, side lunges, banded abduction
- ·For nipple chafing: tape, nipple guards, or anti-chafe balm before long runs
Supportive gear
- ·Supportive briefs or compression shorts if bouncing causes discomfort
- ·Well-fitted running shorts — seams that rub the inner thigh cause groin-adjacent issues
- ·See the gear guide for anti-chafe products and shirt fabrics
When it's not just a strain
- ·Sports hernia often doesn't show on standard imaging — sports medicine or pelvic specialist assessment helps
- ·Inguinal hernia: visible bulge in groin with lifting or straining — surgeon consult before heavy training
- ·Chronic groin pain beyond 6–8 weeks needs structured rehab, not repeated cortisone shots alone
When to see a specialist
- ·Sudden severe testicular pain or swelling — emergency evaluation
- ·Groin pain lasting more than 2–3 weeks despite rest
- ·Visible bulge in groin or scrotum when standing or straining
- ·Pain that returns every time you add speed — sports physio or sports medicine doctor
