If I could pick your collective brains a little…
Quick background: 41, 203cm, 100kg, back on the bike since April 22 and I’ve trained religiously since then. Raced a bit as a kid, didn’t touch the bike for 15 years, did competitive taekwondo and serious strength training at times.
2025 was a very good season for me. Qualified in 3rd place in my UCI Gravel Worlds Qualifier (first ever mass start race) and came 83rd out of 260 in my age group at the finals (inexperience and a mechanical lost me a lot of places).
Ended the season well, with a brief, acute sciatic pain episode, but then adding a lot (on paper) to my FTP, taking it to 445w, so pretty much 4.5w/kg.
For the last three weeks, I’ve had some pretty unpleasant chronic sciatic discomfort. With the acute episode, I was crippled for a couple of days, hardly able to move, and just as quickly as it came, it went. 6 weeks elapsed, and it returned but in a completely different form.
As soon as it manifested for the second time, I hit the gym pretty hard. Lots and lots of hip mobility work (I have really tight hips and hyperflexible hamstrings) coupled with squats, deadlifts, glute specific work, core work and some upper body work.
This has reduced the sciatic discomfort to maybe 5-10% of what it was, and after a week off the bike, I’ve started again this week with minimal discomfort.
I need to galvanise myself against this happening again. I have a good strength training background, but I’m really weak in my glutes. Always have been, unless I do lots of squats.
The problem is that reintroducing a reasonable amount of strength training adds fatigue that will mean a reduction in cycling volume is required.
This past year, I’ve averaged 12.5hrs a week on the bike. I have my FTP to a point now that I don’t think that I really need to focus on it - I have a very strong aerobic engine, especially in the 5-15 minute range.
I am however a terrible sprinter, with me having broken 1500w only once (1300-1350w is my usual upper limit).
I think that focusing on strength work for a little while will bring that sprint up (it should be 1700w really, at my weight, size and FTP) and hopefully reduce any further sciatic issues.
How would you structure the strength training to balance with cycling and avoiding fitness loss? I have my own squat rack and free weights in the basement alongside lots of resistance bands. I don’t have any machines though.
Essentially, I just want to be a little more robust, edge my sprint up but not lose aerobic fitness.
Any help is really appreciated.
