See the sequence before the sessions
The Royal Navy's Royal Marines joining pathway lists the PJFA before the Candidate Preparation Course. PJFA introduces contact with the InReach team; CPC is a further assessed stage. Your most useful first action is to confirm which event you have been invited to attend, what the current joining instructions require and whether your circumstances change the sequence.
Why the published CPC duration differs
At the time of this review, the Royal Marines joining-process overview describes a four-day CPC, while the dedicated CPC page describes a five-day course. Both are Royal Navy pages. Rather than invent a reconciled timetable, treat the official invitation and your recruiting adviser as authoritative for your own date.
Understand the dimensions of CPC
The dedicated official CPC page describes an aerobic assessment, press-ups, sit-ups, pull-ups, swimming and confidence-and-determination activities. That does not mean an independent website can prescribe exact pass scores, make a medical decision or recreate the environment. The useful preparation question is whether your broad training has become consistent, supervised where necessary and proportionate to your starting point.
Ask the right recruiting questions
If the invitation and website disagree, ask which document governs your intake, what equipment or medical instructions apply and when confirmation will arrive. Keep a single source-of-truth note. Avoid spending money on training framed around an old screenshot or a social-media account that may relate to a different year.
Keep official and independent roles distinct
The Royal Navy decides eligibility, joining sequence and assessment outcomes. Independent coaching, where appropriately staffed, could help with general fitness consistency and education, but it does not replace the InReach team or an authorised training programme.
An exercise to make this useful
Make a one-page timeline: application, interview, PJFA, CPC, orientation and initial training. Beside each milestone write the official source or personal joining instruction you can actually cite.
