It's been hot this weekend. It's always going to be harder to run when it's hot so don't beat yourself up about it. Also, everyone has a crap run every now and again. Everyone. So just put the trainers on and go back out. You will be fine.
Always worth remembering that the answer is always - will always be - slow down.
The single mist important thing to achieve in the C25K programe is to finish. Complete every run and finish every section.
If you cannot finish - you are going too fast, slow down.
If your breathing is laboured - you are going too fast, slow down.
It's OK to run after the gym Ali, if that's most convenient to you. Just slow down and make it a very (very) light jog because the most important thing is that you reach the end without stopping. So if you recognise you're knackered, it's not a problem to just massively reduce your pace.
Not moving fast is not a problem Petra. As long as it's a run (jog) and not a walk. I bet your run is faster than you realise. If you noticed you did some walking and some running in your 5 minutes then there must have been an energy different when you ran, no matter how the speed felt to you.
The answer is still slow down. If you can't finish your 5 minutes at a running pace then then running pace you set is far, far (far) too fast. Slow down. Slow tight down. Your speed when running is totally irrelevant, as long as it's a run/jog. So don't worry if you're slow. You are supposed to be slow. You need to be even slower.
The single most important thing is to finish your running interval without stopping or walking. So set a pace dhow enough from the outset so that you can maintain it.
Slow is fine. Slow run, very very slow run, is better than walking. The answer is always you slow down.
