Had one of those moments today where a 12-year-old asked me why she kept hitting the wall in her 800m, and I realized I'd never actually explained pacing to her properly. Spent twenty minutes breaking down her splits and suddenly it clicked for her. That's the bit nobody tells you about coaching—it's not just about running faster, it's about helping them understand their own body. She's going to absolutely smash her next race.

Just learned the hard way that rolling out your calves before bed actually helps with next-day soreness way more than I expected. Did a brutal 18 miler on Saturday and was convinced Sunday would be a write-off, but spent 10 minutes with the foam roller that night and felt almost human the next morning. Might sound obvious but I've been running for years and somehow never stuck with it consistently.

Just smashed out a 16-miler this morning and the legs felt absolutely brilliant for the first 12k, then reality kicked in and I remembered why I hate mile 13. Had to walk a bit, which is mad because I've done this distance a hundred times, but that's marathons for you - they don't care about your confidence levels. Still ended up doing decent pace though so I'll take it.

Just had one of those moments that reminds me why I do this job. One of the quieter kids in Year 5 finally nailed a pull-up today after weeks of trying, and the look on his face was absolutely brilliant. The whole class started cheering like he'd won an Olympic medal. That's the thing about PE that you don't always get to see in the staff room.

Just learned the hard way that foam rolling your calves for 90 seconds before bed actually helps with the next day's soreness. Did a 20km run yesterday and woke up feeling mostly human instead of like I'd been hit by a bus. Sounds simple but I've been running for years and only just started doing this properly.

Just got back from watching Leeds United absolutely bottle it against a team that should've been well within reach. Mate next to me nearly threw his pie at the ref, which honestly would've made the afternoon more entertaining. On the bright side, the run home cleared my head a bit.

Had one of those moments today where a kid finally nailed a technique they've been struggling with for weeks. The look on their face when it clicked was absolutely worth every repetition I made them do. That's why I show up on Saturday mornings, honestly.

Just finished 18 miles this morning and the last 3 were absolutely brutal. Legs felt like concrete but that's when you find out what you're actually made of, isn't it? Days like this remind me why I bother with all the easy runs in between. Can't wait to do it all again tomorrow, which probably means I need my head checked.

Had one of those moments today that reminds me why I do this. One of the under-14s absolutely nailed a jump he's been struggling with for weeks, and the pure joy on his face was just brilliant. He turned to me and said "I told you I could do it" – made my whole week, honestly.

Just finished a brutal 16-miler this morning in the rain and honestly felt like I was running through treacle for the first 8k. Then something just clicked and the last half flew by. Those are the runs that remind me why I keep doing this, even when my knees are screaming at me.
