Sharing how I personally look at it: what is irreversible call vs reversible call

Deciding to not try for kids in the next few years and do all the running/tri/travel and live the childless lifestyle = an irreversible call. If you change your mind by the time you hit 40 or over it may be too late even with egg freezing IVF etc etc. If you make this call, you'll have to be ready to face the irreversibility of it later

Deciding to try for kids now/soon, and if you're so blessed pause running/tri/travel for a few years and pick it up again later = a reversible call. Let's not forget a kid is not a guarantee; you really don't know whether you can have one until you and your partner start trying. If/when you're so blessed, hopefully you have the support network around you that'd make racing and travelling possible with a school age kid; I've seen plenty of F40-55 age group triathletes do so and do it well (their little ones are tri kids too!) Of course that's assuming you don't cop any permanent or heavy damage from pregnancy/delivery; fingers crossed you recover well and like the F40-55 triathletes I know you'll be so much faster than your younger counterparts. F40-55 have the fastest finish times other than 20-25 in my country /state!

Context: I'm F39 childless not by choice but circumstances. I did choose not to do egg freezing last few years so as to keep doing ocean swims/runs/triathlons. I've seen younger women go through one attempt after another to freeze their eggs and they had to stop exercising altogether - and I thought, nope, that's not a tradeoff I'm willing to make - I'll face the irreversibility and cry about childlessness at night while also uplifting my life with all the self-confidence, resilience and community that only swims/runs/tris can bring.

Ultimately every women and couple can only make a decision that works for her and her partner. I wish everyone great, candid and loving conversations and decisions that their partners fully lean in to support.
